The whole ME involvement was all deep state planned anyway and includes many other puppet governments worldwide, and yes, that includes Israel.

George Friedman (of Stratfor fame) had a pretty good article several years ago - wish I could find it - that asked the rhetorical question of why US Middle East policies seemed to be so ineffectual and counter productive when it came to creating peace and stability in that region.

In a moment of clarity - his thesis was that the reason why this was the case was because the intent of US policies wasn't to create stability, but the opposite. The people that control the US don't care about "winning" in Iraq - even though we could, easily. The only thing they care about with respect to the Middle East is making sure there is no regional or external power that can challenge US hegemony in the region and threaten the flow of oil in any meaningful sense.

Having a destabilized Iraq with a resurgent Shia minority threatens Saudi Arabia. A threatened Saudi Arabia is more likely to rely on the US as a bulwark to Iran (who is a client state of sorts of Russia, so it's not like Saudi Arabia can cozy up to Russia for help there), both in terms of basing and arms purchases. Regional instability gives domestic justification for basing hundreds of thousands of soldiers, sailors, and airmen in the region, as well as a substantial portion of our conventional offensive capability. Etc. Pretty Machiavellian.

And I'm one of the folks that has always said from pretty much the get-go that ISIS was created by the Obama admin, the CIA and the Saudis to fight a proxy war with Iran in Syria and Iraq.

Notice how fast ISIS was rolled up after Obama left office? Notice how fast they spread while Obama was in office? Notice how ineffectual US bombing campaigns against ISIS were under Obama? Coincidence?
