US Defense budgets and military personnel strength are in steep decline and will be for years to come due to sequestration and other cuts.
I assume you mean the 2013 cuts -- those have been matched, basically dollar for dollar, by increasing the "temporary" budget for Afghanistan. US military spending remains outrageous, at about the level of the rest of the world put together.
The US was attacked on 9/11 because of existing religious extremism and anti-Americanism, not the other way around, the US didn't cause it.
Fundamentalism is a part of it, yes, but would never amount to anything like what we've seen were it not for widespread anti-US sentiments stemming from more pragmatic reasons, such as US foreign policy for the last, oh, seven decades. 911 was a scandalous crime, no doubt about it, but to state that it is completely unrelated to your own actions is patently false.
It is baffling how you could get such simple questions so wrong. Substituting slogans for facts and thinking?
Coming from someone who apparently still believes the Iraq war had anything to do with 911 other than rhetoric, and somehow still manages to delude himself that anti-American sentiment somehow thrives in complete isolation of its international posturing -- yeah, baffling is what that is.
