Iran seized a South Korean tanker and arrested its crew in the Persian Gulf on Monday as the US military reversed itself and ordered the nuclear-powered aircraft carrier USS Nimitz to remain in the region.
The reversal of the Nimitz's orders over the past five days alarmed several NATO officials who have repeatedly expressed concerns about what they see as erratic US national security moves post-election. 

"I suspect they will say there was new information or a new threat and that the Nimitz was needed to stay in the area but there will be widespread suspicions that Trump overruled the redeployment for his own political or emotional concerns," a NATO official told Insider.
