1) On the internet, everybody is glorifying the Ukrainians who are fighting Russia back and calling them Heroes and supporting them in fighting Russians (And to make it clear I agree that they should fight back and not give their homes for free). On the contrary, I saw no such things for Irak people when they manage to kill American soldiers or destroy their vehicles. If anything, they probably were called terrorists, I am not sure tho. Why didn't the western people support (with thoughts and prayers at least) the Irak people in fighting back the Americans ? Why didn't they call them Heroes ?
Because the resistance in Iraq was very, very different. We knew that from the get-go. We all knew that the Iraqi people were living under the brutal dictatorship of Saddam and we knew that they would not be very supportive of him when shit would hit the fan; but we also knew that once Saddam was gone, the various social, ethnic and religious groups of Iraq would turn on each other and the region would collapse to chaos. Nobody in the west ever liked or supported Saddam, we knew what a terrible person he was, but we also knew that war was not the right way to get rid of him. The ordinary Iraqi population wasn't actually resisting; the regular Iraqi forces folded very quickly. The guys who ended up leading the insurgency were for the most part radical Islamists. Really bad people, who were ready to send their own children to death for the glory of Allah. Unlike the people in Ukraine today, they weren't fighting for democracy, and a lot of them weren't even fighting for their own people. That's why we didn't consider them heroes.
2) Everybody is making Putin look like a super villain almost on the same level as Hitler and saying that he should be removed / exciled / jailed, but when George Bush did the same people were much more forgiving (I know he is still hated to this day, but not to the same level as Putin), they even elected him again in 2004. I understand that Putin is a dictator, and Bush was not, but still, it seems strange to me.
Obvious reason: Because Bush was a democratically elected head of state (the elections were problematic, but he did leave after eight years), whereas Putin only pretends to be. However:
I have more where that came from.
3) People are almost not allowed to say that they support Russia, I have seen on LinkedIn some Indian CEO or executive sayting that he supports Russia and Putin, because when the West turned against India, Russia supported India. I have seen people calling him out in the comments saying that this is disgraceful (some people disagreed with him respectfully tho). Did people who supported Bush or USA back then receive the same amount of criticism ? As far as I know, No.
There is more at play here. Russia has been internationally isolated for years, it is a country that subdues its own population. Critics of Putin have been murdered. The Ukraine War was essentially the last straw, but Putin was a pariah before that. Putin had started a war in Georgia before this and he illegally annexed Crimea. The protests weren't this hard, then. It's a cumulation of outrage at many, many, many years of Putin despising international law and showing his contempt for independent nations.
The Iraq War was wrong and I still think Bush was a monster for having started it - but he left office after eight years (Putin has been in power for 22 years now), and the Iraq War was very, very different in many ways from the one in Ukraine.
