Why is the administration that wanted to end “forever wars”, wanting to embark on another ill advised adventure.

For the curious: The article doesn't name the ally, but is probably referring to Qatar, which hosts the Al-Udeid Air Base, where the USAF has a significant presence. Geographically, the US could potentially strike Iran from Qatar; they are only separated by the Persian Gulf.

I wonder if there’s a war prize.

A Middle East without the current Iranian regime would be unrecognizable.
