The greenies have been crying for years about the amount of CO2 in the atmosphere. They say that CO2 is a "greenhouse gas" which absorbs the infrared heat the earth is trying to radiate into space, thus warming the earth and the root cause of GLOBAL WARMING. Analysis of ancient air bubbles trapped in arctic icecaps shows the CO2 content in ancient times was around 300 parts per million (PPM) Analysis of modern air shows a CO2 level of 400 PPM. A 25% increase, which the greenies say will lead to the heat death of the earth day after tomorrow. Or sooner.
The greenies claim that the CO2 increase comes from burning coal starting with the industrial revolution (1750 or so) and burning oil starting with the development of the automobile (1900 or so). To halt the CO2 growth the greenies want to put us all back in to a Hiawatha lifestyle, no cars, no oil furnaces, no electricity after dark, and a bunch of other uncomfortable ideas. Gotta save the world you know.
In actual fact, the air is also full of water vapor. Which is as strong a greenhouse gas as CO2. And there is a lot of it. About 11,000 PPM give or take a scosh. It varies from time to time as we all know, some days are very humid others are bone dry. Take 50% relative humidity at 20 C as representative. An increase of 100 PPM of CO2 compared with 11,000 PPM of H2O isn't going to matter for world temperature.
The greenies are getting all hot a bothered by a 1% increase in greenhouse gas in the air.
Relax people, we can drive our cars, travel by air, light our furnaces, and generate electricity and the planet will be just fine.

Putting a nuclear warhead on a missile
Pundits have been on TV claiming that making a nuke small and light enough to go on a missile is very difficult and it will take the NORKs years to accomplish it.
I doubt it. The first nuke, the one we used on Hiroshima was so big and heavy that it was all a B29 could do to get off the ground with one on board. By the 1950's we had one small enough to fire out of an 8 inch cannon. Which is small enough to fit on any missile. At least any missile bigger that a 4th of July skyrocket.
The NORKs probably have a little work yet to do before they can nuke the western US, but not much. Secretary Tillerson is saying the right stuff about the NORKs and their nukes.

54.5 MPG. No way
That was Obambi's fuel economy regulation. Trouble is, nobody will buy the resulting automobile. Heck you cannot get 54.5 MPG out of motorcycle, let alone any sort of decent car. Gasoline engine technology was well understood by the 1950's. We had cars that could do 20 mpg back then. Fifty years later the average car is not doing much better, maybe 24 mpg. No way will the technology get to 54.5 mpg for anything more than a motorcycle.
Especially as the Environmental Pollution Agency limits what they call "NOx" emissions. Air is 20% oxygen and 80% nitrogen. Heat air hot enough, say in an engine combustion chamber, and the oxygen and nitrogen go together forming various nitrogen oxides, nitrates, NO, NO2, N2O4, and a bunch more. Old style LA smog formed when the nitrates mixed with oily vapors and sunlight formed that yellow cloud we used to see over city skies. So, rather than clamp down on oily vapors from leaked fuel, the EPA decided to clamp down on NOx emissions. The only way you do that is lower the combustion temperate in the engine cylinders. Which ruins fuel economy and power. Car engines are heat engines, the hotter you can run them, the better they perform. If we dropped the NOx limit we would get a 10% maybe 20% performance improvement right then and there.
Or we could convert to battery powered cars. Trouble is, the best battery powered cars can barely get you to work and back. And they cost twice what a real car costs. No way could a battery car get you to a ski resort for a weekend, or even to grandmother's house unless grandmother lives right next door. The battery is the most expensive part of a battery car. Nobody dares say what battery life might be, but battery replacement is so expensive that you might as well scrap the whole car and buy another one, new. Plain old lead acid car batteries only last 4 winters. How long will your Tesla battery last?
So, Trump is telling Detroit that he is going to "review" (drop) the 54.5 MPG regulation which allows Detroit to keep making cars that people will buy. Good oh. Right on Donald.
Market pressure is there to get fuel economy up and keep it up, all things being equal, customers will buy the car with better fuel mileage and everyone in Detroit knows it.
And, don't fault people for buying SUV's You need an SUV to get Mom, Dad, the kids, and the luggage onboard. The little econo-boxes are horrible on a long trip with kids. Trust me on this.

Woe to the Republic!
Turbo tax won't run on XP any more. I will have to do my taxes on FlatBeast, my HP laptop running Win 10.

So was Trump wiretapped or not?
Who knows? Certainly his first national security advisor, Michael Flynn, was wiretapped. And Trump's phone call with the president of Mexico was tapped and passed to the media. And probably more that we don't know about. So, when Trump says he was wiretapped, I'm inclined to believe him.
So who dunnit? Again, nobody knows. But loosely speaking, I'd say Obambi did it. Not that I think Obambi himself put on lineman's climbing spikes and went up pole and popped the alligator clips over the right telephone pair. He has a slew of federal employees to do that. And with modern technology you may not have to stir from in front of your computer screen to tap phones and read email. All the 17 Federal intelligence shops worked for him up to the inauguration and perhaps some of them still do. Most federal civil servants are Democrats. It was reported that the rubberstamp FISA court did issue a warrant to wiretap Trump Tower. Media has kinda stopped talking about that, although they haven't claimed it didn't happen, yet.
We did have a couple of Congresscritters claim that they found no evidence of a tap, but they did NOT say it never happened. They just said that they didn't have written evidence in their hands. Doesn't mean it didn't happen.
The newsies love this kind of stuff, it's simple enough that they can understand it. More so than understanding just what the Obamacare replacement bill will actually do. I haven't figured that out yet, and I am smarter than the average newsie. And so they burn up their airtime talking about wiretaps.

Note to Congressional Republicans
You gotta pass the Obamacare replacement act. If you don't, your party is toast in 2018. We voters have been watching Congressional Republicans fail to do squat after winning the house in 2012 and the Senate in 2014. Republicans funded all of Obambi's socialist schemes, they approved his appointments (TWO Supreme court justices!), they failed to pass departmental appropriation bills, and they stood still while Obambi issued outrageous executive orders.
Which convinced many of us that the Republicans have back trouble, namely a big yellow stripe. Lack of stones. Or, they are just RINO's. The electorate is made up of 40% Democrats, 40% Republicans and the remainder 20% Independents who will vote for either party depending upon how well they like them. The Independents voted for Trump this time 'cause the alternate was worse, but there is little love between Trump and the independents. If the Republicans cannot get their act together to pass something, anything, then the Independents won't vote Republican next time. Bye bye Congressional majorities, bye bye White House in 2020.
Time will tell. Do Republicans have any guts? Or are they just RINO's in league with the Democrats?

Hard power vs Soft power
The MSM is trashing the Trump budget for cutting money for the State Dept and foreign aid. The implication is that State Dept cookie pushers somehow increase the power and influence of the United States. Not true. State Dept personnel draw their salaries. Few of them actually do anything constructive. US power and influence comes from our robust economy, Hollywood, pop music, superb universities, the internet, our inventors and entrepreneurs, our amusing and vibrant domestic politics, our rock solid currency, our ideals as set forth in the Declaration of Independence and the Constitution, and the warm and generous welcome we offer to foreign immigrants and tourists. These things, and some others I have missed, create US soft power. The State Dept has little to do with it.
We pay some 15000 bureaucrats at State to handle relations with less than 200 countries worldwide. That is some 85 bureaucrats per country. That's far too many. All they have to do is take care of US citizens in trouble abroad, operate an embassy, and do some straight forward legal intelligence gathering. I think State could manage with a lot fewer useless mouths.
Foreign aid is harder to assess. Clearly a few Yankee dollars passed to the right person can accomplish wonders overseas. Just how many dollars, and who we give them to, are matters of pure judgement. Loyal and experienced US diplomats can get the balance right, some of the time, perhaps even more often than not. We should leave the foreign aid debate to the very few people, like Henry Kissinger, who really know what's going on.
