You aren't really suggesting we as a nation turn the other cheek to ISIS, are you?
As a nation, according to the doctrines of the men who fought and shed their blood to form this nation, we are not to use our military to intervene in the civil affairs of other nations. There was allowance for support through the selling of weapons to other nations so they could protect themselves, but we were not to ally ourselves with other nations so to send our military to fight for them. In this, Trump is 100% spot on with the military doctrines of our founding fathers & the US Constitution that was ratified to secure our borders, not the borders of all the nations of the world.
And I am sorry if you do not like this, however, it is the truth & I prefer to live the truth and not the lies & myths that are promoted by the ignorant masses who are too lazy to actually learn history so not to repeat its mistakes.
