That phrase doesn’t mean much. All it means is that this is an armed group in the Middle East who opposes US and Israeli hegemony. This includes Hezbollah, Hamas, Islamic Jihad, the Houthis, the Afghan Shia militias, and the PMF division of the Iraqi Army.
None of those groups takes orders from Iran. The group that we bombed does not take orders from Iran and they receive neither funding nor weapons from Iran. They are simply allied with the Iranian government.
In the case of the Houthis, there are Iranian advisors embedded in the group that help them plan and carry out some attacks. Iran sends weapons prototypes of missiles, rockets, and drones and then the Houthi modify them into their own native products. There are also Iranian advisors embedded in the Houthi forces.
In addition, Iranian advisors help the Houthi carry out some attacks. For instance, Iran helped plan and carry out the Houthi attack from Yemen against the Aramco oil refinery in Saudi Arabia. The US said Iran launched the attack from a base in Southern Iran, but that’s not true. We made that up because we would rather blame Iran than the Houthis for the attack.
It is important to realize that the US government, especially the State Department, CIA, and Pentagon, lie constantly when it comes to US foreign policy against nations we consider our adversaries. And all major US news organizations get a lot of their foreign policy stories directly from the CIA.
Look up Operation Mockingbird. In this plan, the CIA had most of the top journalists in the US on its payroll, so in essence, the CIA was controlling almost every major press organ in the US. The owners of these media groups knew that they were under CIA control, but they didn’t mind because the US media always agrees with whatever aims the CIA and State Department has as the CIA and the American ruling class and corporations share the same aims. When it comes to opposition to US foreign policy in regard to our adversaries, there is no major opposition media in the US. Our press is as controlled as PRAVDA was in the USSR.
That is why it is important to be dubious to say the least about any foreign policy news story you read about a nation deemed an enemy of the US. Every single story you read about that country or group is going to be propaganda in one way or another. Stop believing the US media! Stop believing the US government! Stop believing the Pentagon! They’re all lying to you.
