Sir Keir Starmer has come under fire from both American and Israeli officials after criticizing Israel's plans to escalate military operations in Gaza. The Prime Minister and senior US figures have warned Israel against taking control of Gaza City, while Starmer called for a ceasefire, increased humanitarian aid, and a negotiated solution. In response, Washington's ambassador to Israel harshly criticized Starmer, suggesting he should 'sit this one out' and drawing controversial historical comparisons. The debate comes as Israel unveils new military principles for Gaza and the US reiterates its refusal to recognize a Palestinian state, highlighting ongoing divisions between allies over the path forward in the Middle East.
