President Biden will travel to Israel on Wednesday to show solidarity with America’s closest ally in the Middle East, in a wartime trip to bolster the country’s resolve to eradicate Hamas but also to urge limits on what seems bound to be a casualty-filled ground invasion of the Gaza Strip.

It will be a trip fraught with risks, both political and physical.

The White House announced the visit on Monday evening after Mr. Biden met with his top intelligence officials and his closest advisers in the Oval Office to debate whether to accept the invitation that Prime Minister Benjamin Netanyahu extended over the weekend.

In a briefing to reporters Monday night, John F. Kirby, a spokesman for the National Security Council, said Mr. Biden would focus on “the critical need for humanitarian assistance to get into Gaza, as well as the ability for innocent people to get out.”

He said the president would have meetings in Tel Aviv and in Amman, Jordan, with the leaders of Jordan, Egypt and the Palestinian Authority.
