In order to prevent the fanatical regime from obtaining nukes, the US will employ more aggressive measures. According to U.S. ambassador to the United Nations, John Bolton who said "Iran faces “tangible and painful consequences” if it continues its nuclear activities and the United States will use “all tools at our disposal” to stop this threat".
The US response will be swift and decisive to prevent a nuclear armed Iran from threatening world stability. I predict a draft will be needed to supply tropps to "pacify" Iran and prevent it from continuing its present nuclear ambitions.
Our present geopolitical situation is complicated by Iran being an enemy of the US. Bolton also said "Iran poses a “comprehensive threat” as a state sponsor of terrorism as well as a nuclear aspirant and so “we must be prepared to rely on comprehensive solutions and use all the tools at our disposal to stop the threat that the Iranian regime poses.”
We hope that this situation can be solved peacefully, but in a jump to 2009 using astral time travel I saw Russia threaten the US.
