President Trump is exploring an expanded military alliance with Israel — days ahead of a crucial re-election bid for Prime Minister Benjamin Netanyahu.

Trump announced the possible pact in a pair of tweets just three days before Israel's national elections, set for Tuesday.

A mutual defense agreement "would further anchor the tremendous alliance between our two countries," Trump posted.

"I look forward to continuing those discussions after the Israeli Elections when we meet at the United Nations later this month!"

Under a mutual defense framework, allies agree to join each other's military efforts when one side comes under attack. The U.S. maintains several such agreements — with the members of NATO and with Japan, for example — but has no such formal treaty with Israel.
