WASHINGTON (AP) — Within hours of the horrific attack by Hamas, the U.S. began moving warships and aircraft to the region to be ready to provide Israel with whatever it needed to respond. On Tuesday, more ships and forces were heading toward Israel, and other troops in the U.S. were preparing to deploy if called on. As of Tuesday, five shipments of U.S. weapons and equipment have arrived in Israel and the Pentagon has ordered another 2,000 troops to be prepared to deploy to the region if necessary. The buildup reflects U.S. concerns that the deadly fighting between Hamas and Israel could escalate into a more dangerous, regional conflict.
