Trump will not withdraw troops engaged in the Iran war

US President Donald Trump has said he does not plan to withdraw nearly 50,000 troops from Iran until the ongoing war is 'complete'.

“I don't think (the military) is in danger. We have the best defense we've ever seen. We have the best offensive system we've ever seen. So I don't think it's a danger,” Trump told 'Meet the Press' host Kristen Welker in a wide-ranging interview recorded Friday on NBC and aired Sunday.

“I would say it would be foolish to do that, because we might have to use them,” Trump added.

Trump compared the casualties of the Iran campaign to the US war in Vietnam, in which the US lost more than 58,000 troops.

“We've lost 13 here and that's a lot. 13 is a lot. But, if you look at Vietnam, where millions were killed, if you look at any of the last seven or eight wars where a lot of people were killed, we've lost 13. And again, 13 is too many. I don't want to lose anyone. But 13 is less than anyone would have ever imagined. I think we're doing very well.”
