'India-Pakistan had great potential': Trump says Russia-Ukraine conflict is biggest after World War II; criticises Putin

US President Donald Trump criticised Vladimir Putin for continuing the war against Ukraine, saying it was "making him look very bad."

"I don't know why he continues with this war," Trump said. "He should have won that war in one week."

Trump's statement came ahead of his scheduled meeting with the Ukrainian leader, Volodymyr Zelenskyy, at the White House on Friday. Earlier on Monday, Trump said that he is considering sending the US-made Tomahawk long-range cruise missiles to Ukraine.

During a bilateral lunch with Argentine President Javier Milei at the White House, Trump said that he is very disappointed with the strained relationship with Russia and wondered why Putin is continuing the war.

"I am very disappointed because Vladimir Putin and I had a very good relationship. Probably still do. I don't know why he continues with this war," Trump said.

Calling the Russia-Ukraine war "horrible", he said it is "the biggest thing that's happened since World War II in terms of death."

"This war has been so bad for him. He's going into four years of a war that he should have won in one week. He has lost a million and a half soldiers, probably, close. It's a horrible war. It is the biggest thing that's happened since World War II in terms of death," he continued.

Trump further reiterated his claims of stopping eight conflicts, including those between India and Pakistan.

"It's (Russia-Ukraine conflict) bigger than any of them. I settled eight of them. The biggest is that in terms of death. I think India and Pakistan had great potential, too. We did a great job in that one. But he's got to really settle this war," he said.
