If Putin claims victory in Ukraine then he may go on to invade, annexe and conquer other parts of the world, warned former Republican presidential candidate and prisoner of war in Vietnam John McCain.
Fellow Republican Mr Graham also issued a damning statement to Mr Putin, saying: “I admire the fact that you will fight for your homeland.’
“All of us will go back to Washington and we will push the case against Russia. Enough of a Russian aggression.
“It is time for them to pay a heavier price. Our fight is not with the Russian people but with Putin.
“Our promise to you is to take your cause to Washington, inform the American people of your bravery and make the case against Putin to the world.”
“We have succeeded not because of equipment but because of your courage.
“So I thank you and the world is watching and the world is watching because we cannot allow Vladimir Putin to succeed here because if he succeeds here, he will succeed in other countries.”
