You are mostly right.
The Republicans have done all the terrible and stupid things you quote. Although I don't know that I am giving chemical weapons to Saddam.
One can rightly say that the Republicans set fire to the already tense situation in the Middle East.
The Arabs were always on the neck in the region and the Republicans simply gave them more ammunition and made things worse.
My point is that the Republicans in the Middle East have not triggered terrorism, but they have fueled the fire.
When it comes to the security of American sovereignty, I don't understand why the Republicans say they keep us safer than Democrats.
September 11th occurred during Bush Jr., and sporadic terrorist attacks on US soil have occurred in the past three presidencies and possibly further back.
