The threat posed by a potential nuclear Iran is no laughing matter.
But neither is the escalating threat of a nuclear exchange between the US and Russia.
They are collectively in the process of ending their mutual nuclear restrictions and developing new, more advanced nuclear weapons which could be used against each other.
As things stand, the US last week formally exited the 1987 Intermediate-Range Nuclear Forces (INF) treaty which had eliminated around 2,700 US and Soviet nuclear weapons on the European continent, and may exit the new Strategic Arms Reduction Treaty (START) in 2021.
START, which replaced older nuclear treaties between the countries that have been running for decades, had limited the US and Russia Since 2010 to 700 deployed missiles and bombers, 1,550 deployed warheads and 800 deployed and non-deployed launchers.
Following exiting the INF, America is expected to test a ground-launched cruise missile in the coming weeks. And in November, the Pentagon plans to test an intermediate-range ballistic missile.
