Where are you getting 7k from? Iraq Body Count [0] reports closer to 200k. Even if you use [1] to limit the death count to those caused by coalition forces, you get more than 7k just in 2003. Before you try to discredit it, the main criticism the project has received [2] is that it's undercounting.
The current Ukraine civilian death count is only up to 1.5k so far [3], so Russia's got a lot of catching up to do before it can compete with what's happening in Iraq (though I truly hope it doesn't).
This includes the casualties of the insurgency and civil war in the years after the invasion.
The Iraq Body Count project (IBC) documented a higher number of civilian deaths up to the end of the major combat phase (May 1, 2003). In a 2005 report,[86] using updated information, the IBC reported that 7,299 civilians are documented to have been killed, primarily by U.S. air and ground forces.
The current Ukraine civilian death count is only up to 1.5k so far [3], so Russia's got a lot of catching up to do before it can compete with what's happening in Iraq (though I truly hope it doesn't).
