The Biden administration says Israel hasn't crossed a red line on Rafah. This could be why

The Biden administration has gone to lengths to avoid any suggestion that Israeli forces have crossed a red line set by President Joe Biden in the deepening offensive in the southern Gaza city of Rafah. That includes administration officials calling Israeli military operations around Rafah an “uptick.” The administration says Israel has changed its approach, going for select, limited strikes that reduce civilian deaths. Biden said early last month that he wouldn't supply offensive weapons if Israel launched an all-out assault on Rafah. Critics say Biden has come up against a domestic red line of his own — namely, challenging ally Israel in an election year. And they say he's decided not to cross it.
