Donald Trump has given yet another below-par performance that will annoy everyone who cares about foreign policy, writes Jonathan Bernstein.

US senators like to participate in governing, as opposed to showing up and having their vote tallied in support of their party and Trump would do well to remember that says Jonathan Bernstein.

Any US president’s influence is based on his reputation among Congress, bureaucrats, and other elites, and the White House incumbent has rapidly damaged his, says Jonathan Bernstein.
