this could all get out of hand tbh . to many players , all with there own agenda are involved
Iran
Israel who have concerns about Iran & seem to be aligning with the Saudis who also have concerns with iran
Turkey who seem to be getting ever closer to the Russians
Russians , with out who's help Assad may well have been toppled
Hezbolah from the Lebanon
USA
All = a S*** sandwich & possible military confrontation between the US & the Russians

so what ever military force is used by the US will be proportionate

& a token gesture ,so it will be a waste of time
imho they should stick a few 100 cruise missiles onto Assads palace residence

that may get his attention

hit the main Russian military base with a missile salvo
either that or just mind our own bussiness
