The Biden administration is reportedly seeking to encourage “land swaps” between Israel and the Lebanese Hezbollah. The White House is hoping to prevent a wider war between the Jewish state and the U.S.-designated terrorist group. But history is clear: Concessions don’t deter Islamist terrorists. They embolden them.

Amos Hochstein, a Biden administration envoy, visited Israel this week. He was there to avert a greater war between Hezbollah, the Iranian-backed proxy that de facto rules Lebanon, and Israel. Hezbollah has been launching rockets into Israel, resulting in several deaths. Israel has been taking targeted action against Hezbollah officers and forces, most recently with a remarkable attack on Hezbollah’s pager network on Tuesday. But Hezbollah is the problem here.
