It's OVER 5,000!
Here's what I believe. If I walk up to you in a bar and punch you in the face, then there should be a reasonable expectation that you or your friends might punch me back.
If I kill a man, there should be a reasonable expectation that his family may want revenge.
It's called "blowback." A common term used by our CIA. And many of the attacks we have suffered have been attributed to blowback per our own government (such as a 9/11). Osama explained the reasons for 9/11. Go check them out.
You can't just impose your will on other countries and not expect some sort of reaction. We've been doing for over a century. Now, when they fight back, we call them terrorists, and kill more of them. So more of them fight back. And we kill more. We're their best recruiting tool.
It is an undeniable fact that they want us to bomb their areas more because it is the best, easiest way to garner recruits against us. There are a ton of problems over there, and if we were to back off for decades, it would hardly solve it. But we definitely play a hand in it, and have for a while. We've been involved with different groups/countries for so long, sometimes supporting them, and then later fighting them. We're pretty damn corrupt in our own ways. We are undoubtedly responsible for some of this crap against us, and in general over there.
