Even w/ the all the ISIS propaganda and past finance of them hasn't gotten Americans as a whole to want to get deeply involved despite the major economic interests are so gun-ho in favor of intervention. Many in the GOP have been juiced up by non-stop Fox coverage of ISIS for intervening somehow and w/o Rand Paul saying his piece, this number would be even larger. I hardly doubt Americans will give a crap about what's going on over in the southeast Asian territories if they are even aware of what is going on. Of course, the government usually does what it does in spite of the populace at times so who knows.
Don't underestimate the role of propaganda to vilify the 'enemy' and have the populace rally around the cause. Even so, the general public is quite ignorant on most of the foreign policy stuff and that doesn't stop anything us from getting involved. Containing China is of strategic importance because it's the only country with the economy that could support a navy large enough to rival ours. Unparalleled control of the seas has been the biggest military and economic advantage America has had in the last 70 years. If it becomes necessary, you'll see the government's push to rally the public around 'protecting our allies.'
