The Bahrain–Israel normalization agreement,1 officially Abraham Accords: Declaration of Peace, Cooperation, and Constructive Diplomatic and Friendly Relations2 is an agreement to normalize diplomatic and other relations between Bahrain and Israel. The agreement was announced by President Donald Trump on September 11, 2020,3 and followed on from a joint statement, officially referred to as the Abraham Accords, by the United States, Israel and the United Arab Emirates (UAE) on August 13, 2020. It was formally signed on September 15, 2020, at the White House in Washington, D.C., and made Bahrain the fourth Arab state to recognize Israel and the second within a month.
Putting aside whether this is actually good for Middle East peace, since only time will tell, some proponents of the arrangement have lauded Donald Trump personally for the signing of this deal.
In the background section of that wikipedia article we learn that Bahrain ended boycotting Israel in 2005, showing some softening long before Trump was a politician. However, all subsequent developments in that timeline are during his presidency. I also understand that Trump has a peace plan for Israeli/Palestinian peace, but that seems perhaps not related to this.
What I'd like is a brief analysis on Trump's and his administration's involvement in the Abraham Accords. I'm interested in a fair analysis backed up with facts and citations. If possible, a "percentage of credit" synthesis would be helpful.
