Imagine Russia, China, Iran and North Korea together have sent an armed to the teeth armada of war ships to the coasts of Florida or/and California and they are cruising up and down near USA territorial waters claiming to have the right to inspect ALL USA ships leaving and coming into USA for "weapons of mass distractions"(this is what is happening near Iran's coastal waters and near China's).
Imagine Russia, China, Iran and North Korea together constantly threatening to bomb USA if USA doesn't close down all its nuclear power plants because USA *might* be producing nuclear weapons. Yet neither Russia, China, Iran and North Korea have produced a shred of evidence USA is doing what they are claiming.
Imagine Russia, China, Iran and North Korea together have used their political clout to impose crippling economic and political sanctions against USA. Imagine they are threatening to place even more sanctions against USA if USA doesn't do what they want it to do IE close all its nuclear power plants and opens up all its weapons making facilities for inspection.
Imagine Russia, China, Iran and North Korea together meddled directly into USA's elections and political system, going as far as overthrowing the rightfully elected government and helping the Queen of England take over USA because USA used to be a British colony after all. (that is exactly what happened to Iran in 1950, learn your history, kids)
Imagine Russia, China, Iran and North Korea together are constantly bleating about how dangerous USA is and are claiming all sorts of bullshit about how USA wants to attack them with "weapons of mass distraction" because after all: "USA's president is an unstable nut case".
Can you imagine all and any of that? If you can, then now you know just how Iran, Russia, China and North Korea feel about USA.
