Relations With Iran 'Courteous, Professional'

At least on the high seas, according to DefenseLink:

Despite political tensions among Iran and other countries, exchanges between the Iranian navy and coalition forces in the northern Arabian Gulf are "fully courteous and professional," said U.S. Navy Capt. Christopher Noble, during an interview here.
Noble, the commander of Coalition Task Group 58.1, is charged with protecting Iraq's oil terminals, located in Iraqi territorial waters.
However, exchanges with ships manned by Iranian Revolutionary Guardsmen are not as professional, and the Iranian ships test the coalition on occasion.

Soldiers generally get along better than politicians.
