Syria is not a threat to our national security but Iran is.
To some extent, going after Iran is also going after some of Syria's resources thus killing one and a half birds with one stone.
Do I think we should declare war on Iran out of the blue? No. But there were times when serious red lines were crossed by Iran but we ignored it, just like the last North Korea fiasco.
During the last North Korean fiasco we could have told China to disarm North Korea of what it has already progressed to with its nuclear weapons program or we will.
Can't do any of that now and be taken seriously. If we did, they would likely assume we were drawing another fake red line which could by default draw us into war simply because we have no credibility.
We need to choose our red lines wisely and on those nations and situations that involve our national security.
I don’t see Iran as a threat in a military terms. They are an extremely complicated society, much more developed than any of the Arabs. There are a lot of open minded people who aren’t happy with the mullahs and certainly not dreaming to kill Americans.
Do you think they are about to occupy America or what?
