The aggressor makes the rules. Russia is the aggressor again. They want to compare what they are doing with what the US did in Iraq.
The US enforced a UN resolution that Saddam stuck his middle finger to the world at. The invasion was legal. He threw UN inspectors out who had a legal right to be there, and pounded his chest at the world bragging about having nuclear power.
The US and UN offered Saddam exile before they invaded and he turned them down. He was a fool, because he is dead now.
Now Russia and Iran want to be fools too. What will they accomplish?
There is no way to defeat the USA, because we are free people who will volunteer to fight when it comes time. Others have to force people to fight. These foolish countries will never learn. They are cowards. Ben
