The Iranians would enjoy an initial strategic advantage from advanced mining and home field. However, while we would be able to overcome that, they would then deploy suicide boat attacks, which may cause our ships to have some radar problems. Also, don't forget that they've been purchasing advanced subs from the Chinese. So, we'd lose some people initially, then it comes down to whether we'd listen to the pussy liberal scumbags in this country when they start whining about pulling out.
Thank God these people weren't around in mass numbers during WWII.
