2020.08.13 UAE and Israel
AP completely discredits itself by calling this "a rare diplomatic win". If a Democrat Administration had brokered a massive diplomatic coup that ended the gulf Arab blockade against Israel (or roadmap for one), and got Israel to stop annexation plans in the West Bank, they'd being trumpeting this historical event. But they're trying to downplay the historic event, because it was done by Donald Trump.
Off the top of my head, Trump's prior diplomatic wins include: renegotiating NAFTA (USMCA), renegotiated trade with China (major concessions), got us out of the WTO, got sanctions re-established against Iran, opened direct discussion on denuclearizing North Korea, got Mexico to enforce our border, pressured "allies" into increasing NATAO/defense spending, got Japan to quadruple their defense payments, recognized Jerusalem as the Capital of Israel, Destroyed the ISIL/Islamic State caliphate that rose under Obama, killed its terrorist chieftain (Abu Bakr al-Baghdadi), pulled us out of multiple foreign entanglements, and so on. You don't have to like or vote for him -- but diplomatically -- if you look at American interests?
He's way ahead of Obama in half the time. No Benghazi, no red lines he backed off of, no rise of the caliphate, no bowing 8 times to other heads of state, no going to Hiroshima during their remembrance (against the advice of their foreign minister) and making us look bad, no Russian invasion of Ukraine under his watch, no collapse of Egypt or Libya (with our help)... so foreign policy wise? Just not doing bad things was a foreign policy win.
