Totally unrelated and for some reason it may have an effect to the market especially to the nations in concern. COVID-19 was way more global compare to the war happening now at Gaza, I don't think there will be a crash in the market because it will spread in the Middle East, not that fast I guess.
Not that fast for sure it has been happening for some time now and it has hardly had an impact, while the pandemic was leading to gross downtrends in all markets, I made very cheap stock buys during that time which have rebounded back to massive profits today. That was a time for bitcoin to crash as well, but as far as I recall, it did not get affected much. Rather negative news of exchanges and hacks impacted it more deeply.
I still dont understand the context of "War Crimes" here and why the OP included that in the thread title. Even then just like Russia-Ukraine war I dont think this one will impact much, but only time can tell.
