1. "Global Warming" is not the threat that people make it out to be. It is a mildly interesting phenomenon, but one that we have virtually no affect upon as human beings (as far as we know through our current science). According to the actual, hard science, we also do not know if our world is even in a warming period or a cooling period at this very moment. The science is simply too unclear. All we can say for sure is that climate change has always existed on the earth and that it never hurts for us to keep it in mind (just so long as we don’t politicize it for selfish reasons).
2. If human beings are polluting the environment in unsustainable ways, increasing the global CO2 levels is probably not one of them. Though I think we can all probably agree that pollution from our cars and factories is still undesirable (plus, I don't like how we're consuming all of the "fossil fuel" on our planet), and so it would be a good idea to invest our time and money towards discovering real alternatives. What we need to remember though, is that placing a handicap upon our economy in nonsensical ways (like with "Kyoto") will only slow down our technological progress, not speed it up. If we want a technological advance, then we should encourage it in positive ways.
3. The war in Iraq was a very good thing because Saddam was a sitting upon lots of oil and that oil was going to translate into wealth and that wealth would have equaled far too much danger. Unfortunately, the Bush administration didn't want the war to be about oil (as it actually should have been) and now we're fighting a much more questionable battle today.
4. The Islamic world is pathetic and not worthy of our fear. The sane nations should be fighting to kill their warriors and their ability to threaten freedom. If we win, it would be a nice blow to Islamic moral as well. Fighting to give them democracy and "freedom" is obviously a nice goal, but not one that I believe we can accomplish in the way that we are currently fighting. I believe that, at best, we can only take actions that will support democracy in that area of the world. All people (no matter their culture or where they live) can eventually see clear costs and clear benefits when they are presented. We cannot force democracy to exist where it will not first be appreciated in that fundamental way.
5. The Islamic world is inferior to the Western world. On the whole, they behave irrationally at every turn and cannot be reasoned with regarding reasonable issues. They not only frequently desire and frequently act to kill us, they also frequently desire and frequently act to kill each other. Their countries are ruled by murder and intimidation. The best course of action to take against that kind of evil would be to contain it as best we can (while encouraging good behavior as I stated in my previous point).
