The scale of death and devastation from the war in Gaza is comparable to 2 nukes, like hiroshima, so it is not Islamist -Marxist threat, the most deadly and dangerous thread working at the moment. Imagine the US military hunted a ghost of thread, without finding it in Iraq. And after it was discovered where these exact same WMD, possible are in storages. They just watched how they are being used and their effect on the battlefield.
“Red lines” for the US-Government, maybe it is not what others think of it. And is nothing else than, they just mean by saying the watch very closely, is just they trails of blood, instead of the shed of it to stop? Let’s hope that is not the truth meaning of it.
