The series of Arabic states opening diplomatic relations with Israel was definitely American-led.
Israel's usually pretty opaque military and other actions allow for a lot of unexpected partnerships.
The Abraham accords are the legacy of the Trump admin and I think it’s a very good one.
As alliances shift in the middle east it's not surprising that Israel would be involved. Relations / tensions are pretty wild in the Middle East. I think 'unlikely' alliances are almost inevitable, and maybe not as unlikely as we think. There area lot of strangely conflicting incentives out there.
I think whatever horse trading happened behind the scenes was likely more valuable than PR.
