Sensible, if assets are at risk of being stranded.
Is there enough to matter?
Sensible, if assets are at risk of being stranded.
Sensible, if US needs all of its own consumption to solve all of its own problems. (They get to define their own problems and solutions; others do not get to dictate.)
Etc.
The US can't afford a bespoke compartmented commitment for each multi-lateral defence arrangements it has. In effect it needs to be able to employ all its assets worldwide, if there is to be any hope that it will continue to supply a modicum of security worldwide.
The problem here is that Israel and the US each have an "Iran problem" (different for each, more pronounced for Israel) that they have been almost entirely left to solve themselves. Now they're solving it, in ways that others would prefer they don't. In solving it, they're creating "Iran problems" for others. And they're leaving others to solve for themselves...
