Well Saudi Arabia shouldn't prove too much of a puzzle - as the USA and UK have both committed to large scale weapons sales (pretty much injecting war probability into the region - and almost certainly precipitating the Qatar crisis - a maneuver against Iran).

As for Afghanistan and Iraq... those remain something of a puzzle... unless the intention is to let in particular, relatively easy to direct seeds of terrorism (both are stitched-up war zones whose populations have a reason to have a beef with the USA - and I'd be surprised if the CIA presence there weren't also a factor).

Still... this is speculation...

Even so - there exists a consistency issue with this list of nations. 'Something' is up.
