This week an article in the Hebrew language newspaper Ha'aretz reported that Israel had agreed to the use of the Iron Dome missile defense system at US bases in the Persian Gulf. Iron Dome is a joint Israel-US project, so both sides need to approve sales.
However, it isn't clear that this arrangement applies to the use of Iron Dome systems by the US military (it does not). Ha'aretz may have been trying to stir up controversy; there is no evidence the US intends to deploy the two Iron Dome systems it purchased, except for testing.
But the Ha'aretz article has ironic importance because it illustrates that the US has a very limited, almost non-existent capability to protect US bases in the Middle East or elsewhere.
