Pretty much. I can't provide a video of our burning any ISIS members alive, and there are no real-time films of inhabitants of Hiroshima and Nagasake being incinerated while alive, but there are plenty of films of the aftermath. I'm sure the films of radioactive burns would be most satisfactory to those who want to see that sort of thing. All brought to you courtesy of 'Murica.
Only a complete moron, imbecile would equate ISIS burning alive a captured prisoner to Hiroshima and Nagasaki. The two are completely incomparable actions.
The ritualistic execution of prisoners by ISIS is much more akin the to ritualistic execution of prisoners by the Japanese using beheading during World War 2 than to the dropping of the atomic bomb. http://ww2today.com/24th-october-1943-japanese-execute-australian-commando-leonard-siffleet
So instead of incinerating them we should have sent teams of professional beheaders? As far as you may want to stray from the original subject, we have in fact "set people on fire". It had nothing to do with beheading.
