Trump threw his full support behind Netanyahu just before an Israeli election, a move critics say breaks the long-standing norm against foreign leaders meddling in each other's elections.

• Trump gave an unusually strong public endorsement of Netanyahu days before the vote.
• The move is seen as hypocritical, since the U.S. has historically objected to foreign leaders weighing in on American elections.
• Trump previously turned on Netanyahu in 2020 for congratulating Biden's election win too soon, reportedly reacting with fury at the time.
• The reversal highlights how personal and transactional Trump's foreign relationships can be, shifting with whatever serves him in the moment.

Outlook: Expect continued scrutiny of U.S. leaders openly intervening in allies' elections, with Netanyahu likely to lean on the endorsement in his campaign's final stretch.
