Willie - I'm not going to quote all of that up there but my response is as follows:
1) Whether a missile defense system works (it doesn't now) isn't really the issue. The issue is whether it is advisable. And while it is in theory a "defensive" system, surely it poses some offensive benefits, such as thwarting a retaliatory attack if the US strikes first, as indicated below.
Any system designed to prevent an attack by taking out incoming missiles isn't an offensive system, I'm sorry that's just a weak argument...
2) We have first strike capacity. You are correct. But the missile defense system would give up first strike capacity with the ability to thwart any retaliatory strike. China and Russia aren't going to let that happen. You're basically starting a new arms race. And China and Russia aren't the only players. And increasing the amount of nuclear material when there is plenty that is insufficiently accounted for and guarded already is just the type of environment that makes a terrorist nuclear threat more likely.
As far as 20th century history, remove the multi-lateral and bi-lateral treaties relating to nuclear arms and tell me what you come up with. Bottom-line: diplomacy works, arms races don't.
What, an arms race to build missile shields, that's probably a good thing, don't you think? Doesn't that defeat the logic for the MAD polices your last point alludes too?
3) I know the Chinese shot down a satellite, which is why we chose to do the same. Once again, diplomacy works. Begin negotiations with the Chinese and the Russian relating to such weaponry and weaponizing space. Why the arms race?
I'm not against any treaties or agreement regarding space, but to cede our hand seems incredibly naive, to be polite.
4) Defense spending accounts for over 50% of discretionary spending (and that is only the Pentagon budget) and we spend more than the rest of the world combined. Given that, surely there are cuts that can be made to the pentagon budget. I also fail to see how it is at all possible that each of the three branches need 33% of overall Pentagon spending. It's not possible that this stuff is necessary. At all.
That's a distorted number, as
defense spending is only 20% of total federal spending. Discretionary spending is only part of the federal budget and not the complete federal spending picture, the largest part of the budget, mandatory spending isn't even included in that figure, it's a real dishonest tactic really, a way to distort the actual percentage spent on defense.
