Also, one big pit is not enough for the Houthis in Yemen; Iran wants to dig more big pits for the U.S. The 2025 Langkawi International Maritime and Aerospace Exhibition in Malaysia also saw Iran showcasing a large number of asymmetric warfare weapons, most of which have been combat-tested in the Middle East. Various drones, rockets, and missiles have all been tested in the Gaza region, on Hezbollah battlefields in Lebanon, and on Houthi armed forces battlefields in Yemen. Some have even struck Syrian and Iraqi U.S. military bases. Iran has also been very thoughtful, as all weapons and ammunition are completely independently researched and produced by Iran, unaffected by any external influences. Iran will not impose additional conditions; once purchased, they can be used entirely autonomously. Moreover, for countries sanctioned by the U.S. and the West, direct contact with the Iranian military is possible, allowing for cooperation in production to avoid the impact of U.S. sanctions. In fact, due to sanctions in previous years, Iranians were not allowed to purchase advanced weapons. Therefore, Iran has always been cooperating with North Korea. Many of Iran's missiles and drones have technical support from North Korea. North Korea has a covert presence in the Middle East. Many of Iran's weapon technologies come from North Korea, and many North Korean instructors have been sent to the Middle East to train anti-American armed groups. The tunnel warfare systems in Hezbollah in Lebanon and in the Gaza Strip bear traces of North Koreans.
