None. However there is a good possibility that that the Israelis will feel compelled to attack Iran’s nuclear infrastructure before the end of Netanyahu’s tenure. willingly or unwillingly there are many scenarios in which the United States would be engaged. The Iranians have purchased state of the art Chinese made shore to ship missiles. The development of these missiles was a strategic priority for China. In event of war with Taiwan (now thankfully unlikely) the Chinese required the means to clear the Taiwan Strait of hostile naval elements. They even managed to obtain American missile guidance systems during the Clinton administration. Those ships have excellent defensive capabilities but it is not clear if they would be effective in such a narrow, shallow location. The Iranians also have asymmetrical offensive capabilities. There are close to ten thousand brave young American sailors alone on the two carriers currently deployed in the Gulf. The fear is the US Navy could face a debacle worse than Pearl Harbor in less than fifteen minutes.
“Chinese” and “state of the art used” used in the same sentence is an oxymoron.
The Iranians are not suicidal. Now there maybe some radicals within their government, but I’m talking about the entire country. The Russians and China are working with Iran too.
