Idea based on Facts: It is all about money..

Don't try to make it look or sound different.All empires where built by taking over "richer but weaker" empires, using strong army (somehow barbarian as well) .. 

Fight over money then collapsed when they got wealthy and (somehow mild mannered) on the hands of another barbarians army. 

Who fought for money..generally people in military are tough or will become tough after the training ..but in general people who have choice (money) will not choose the army as career (few will).

USA learned this 2 facts very well..

It is rich and people don't need to go to military (few do , the others don't have better choice).Well.. Technology is replacing courage this days.. Why not ?? 

If there is money .. We can do it.

They will remain the strongest , with fewer soldiers and better technology ..Let's find ways to compete with them on other issues .. 

Confronting them in what they do best is useless. .. They have the money AND the strength.. 

They don't want to end up like the roman empire..

They like Israel.. Israel knew how to win them.. Others didn't ..

 What can they do to have a part of their money..make them on their side.. 

Are they on the saudi's side ?? Why?? 

Saudis have something they need and Israel doesn't. They just knew how to make them on their side.think of what we win if they will be on our side ??

what can we do to make it happen ?? That's the question.
