Israel has the most powerful military in that region today. They are under no threat lolAgree.
If the US wants to suppress/contain ISIS style activity then we have to supply troops. If the goal is to really crush them then we would need more troops, not less. But the political opposition to the Administration would scream bloody murder if Trump proposed increasing troop levels.
The Middle East is a political/religious/ideological clusterfuck. But there is also a bunch of oil. So the world economies don't get to just ignore it.
No good solutions. Although helping to keep Israel safe/independent is a valid persistent goal.

And the US and Canada have enough oil to supply ourselves for generations ahead.
