Report: Pentagon tracking military cooperation between Iran and North Korea

The Pentagon is reportedly seeing further signs of cooperation between Iran and North Koreaover their missile programs—something Fox News says, "nonproliferation experts have long suspected."

According to the network, such evidence includes similarly designed submarines, missiles, and launch approaches.

As Jeffrey Lewis with the Middlebury Institute of International Studies at Monterey told Fox News, "The very first missiles we saw in Iran were simply copies of North Korean missiles...Over the years, we've seen photographs of North Korean and Iranian officials in each other's countries, and we've seen all kinds of common hardware."

In fact, the Asia-Pacific-focused magazine The Diplomat released a report in April last year about military cooperation between the two countries.

It states that they have "maintained a relatively consistent partnership since the 1979 Iranian Revolution. This alliance has persisted despite the stark contrast between North Korea's strict crackdowns on religious belief and the theocratic nature of the Iranian regime."

The piece argues that they are joined, instead, by the ability to give and receive technical know-how and their anti-American outlooks.

Both Iran and North Korea—along with Iraq—were notably cited by former President George W. Bush in 2002 as part of an "axis of evil arming to threaten the peace of the world."

Experts have more recently grouped the two countries for similar treatment by the U.S., with Robert Litwak of the Woodrow Wilson International Center for Scholars suggesting that the Trump administration sign an "Iran-style nuclear deal with North Korea."

Meanwhile, The Nation's Michael Klare has warned that they could both be vulnerable to preemptive strikes by Trump.
