I think White North Americans have been softened by a lack of participation in the wars that basically every other country in the world are directly affected by. We are a rich nation, but our wealth is exploited by private interests that don't pay enough taxes to reflect that in our national services, military and otherwise.
I think we have to start living in the same world as the rest of the world, and that includes participating in security actions.
But fucked if he's gonna do it on the backs of our working poor. Which includes me. The talk of army stuff is just another excuse for the coming "austerity measures" while the billionaries continue to dine out on our taxes.
