"Trump's past discussion of 'withdrawal of U.S. troops from South Korea' was negotiated."

Federal Senator Bill Hagerty, Republican of the United States, says President-elect Donald Trump's mention of the withdrawal of U.S. troops from South Korea during his first term in office is a businessman's way of negotiating.

Congressman Hagerty made the remarks in an interview with CBS on the 10th local time when Trump mentioned withdrawing U.S. troops from Japan and South Korea while in office.

Hagerty said U.S. troops were stationed in South Korea, Japan and elsewhere when the region's economy collapsed, but today it is a fully developed country, and allies should take action to the extent possible to strengthen their military capabilities.

Earlier in his first term, Trump insisted on raising South Korea's defense cost share to $5 billion, and linked the issue of raising defense costs to the withdrawal of U.S. troops from South Korea, saying that if an agreement is not reached, it should come from South Korea.

During the last presidential election, he called South Korea a "money machine" and argued that South Korea should pay $10 billion in defense costs and 14 trillion won in our money.
