Does America forget that it is currently in several wars?

I am seeing some articles this morning that the US must declare war against ISIS.
Are Americans so disconnected from the fact that the US has been bombing at least 7 Muslim countries and that killing over 1,000 civilians living in Muslim countries may be the best recruitment tool for a group like ISIS?
The Orlando shooter claimed allegiance to ISIS and the Boston Bombers. The Tsaernaev brother who is still alive wrote on the inside of the boat that he was arrested in, that the attacks in Boston were revenge for what America has been doing in Muslim countries and killing innocent civilians. Several other terrorists that were arrested were quoted saying something similar.
Why do we overlook the possibility that our foreign policy is causing blowback, and our involvement in overthrowing dictators and installing American backed leaders may be causing unintended consequences that we are not considering?
