With Israel's campaign against Hamas raging, the United States has renewed calls to work toward a Palestinian state, but few expect success now after decades of failure.

President Joe Biden's administration, which has faced heated criticism in the Arab world for supporting Israel's retaliation over an Oct. 7 Hamas attack that largely targeted civilians, has in recent days subtly changed tone by emphasizing the need to minimize harm to Palestinian civilians.

Speaking Friday on his latest trip to Israel, Secretary of State Antony Blinken called for "humanitarian pauses" to let in assistance and said that longer term a two-state solution was "the best viable path — indeed, the only path."
