There's a reasonably high chance that SARS-2 covid virus leads to a minor or moderate decrease in average lifespan (due to the effects on the vascular system and wreacking havoc on all sorts of organs) and that it will continue to circulate in humanity forever.
If that's the case it'll just slowly outscale any singular event like the Iraq War over multiple human generations of deaths and damage.
Based on what exactly? According to Wikipedia, the Iraq War produced a total death count of 25,071 and a total wounded count of 117,961. Also according to Wikipedia COVID-19 has produced a death count of 6,868,964 and an infection count of 674,809,997.
I'm all for complaining about US tactics, but it's 100% incorrect to try and claim that the Iraq War was "worse" than COVID-19.
Iraq only produced a death count of 25k? Do Iraqis not count?
Also almost all of the violence post war should be somewhat attributable to the invasion; we broke the basket to secure oil rights (and some argue to also keep the petrodollar as the world reserve currency)
The cost was way more than the cherry-picked stats you present
You seem to assume no Iraqis were killed, which is pretty odd.
In "costly and fatal", I also include that the Iraq War arguably marks the end of the US as the world's only superpower. Both in terms of cost and moral status, it was a huge abdication of status.
Hard to compare, admittedly.
