Do you doubt the abilities of the IDF and JSDF though?
The JSDF? You're kidding, right? It has never seen combat ANYWHERE in its entire existence. The IDF is very good at what it does, but what it does is all done within 200 miles of the members' homes, and other than some TTPs it is not necessarily a model the US can get a lot of useful info from on these issues, considering its policies on such things derive from a bizarre mish-mash of rabbinical dictates and Left-wing European socialist ideals.
It's a complex issue, and US culture is different than any of the examples people want to push forward (all the examples seem to be on the 'pro' side so far, nobody seems to have mentioned that the dogshit-quality Arab armies are chock full of fudge-packers). No doubt we will have a DOD-wide unified policy, although the zoomies, squids, and grunts all live in quite different worlds in terms of risks, discipline, and accommodations.
