Behind the scenes: Biden hasn't spoken to Netanyahu in the 20 days since a tense Dec. 23 call, which a frustrated Biden ended with the words: "This conversation is over." They had spoken almost every other day in the first two months of the war.

Why it matters: Since the Oct. 7 Hamas attack 100 days ago, Biden has given Israel his full backing, with unprecedented military and diplomatic support, even while taking a political hit from part of his base in an election year.
