My sister just returned from Israel.  She bought a t-shirt there which says, "Don't worry America.  We've got your back."   We need to support Israel, just as Israel supports us.  If we look back into American history, we can see more than a few isolationist movements.  They have never advanced us as a nation.  Don't we teach history so that the present will not repeat the past?  We do not need to go backward as isolationists.
