Absolutely not! An assassination attempt on an ex-president is a threat to our national security? Heck we have had government employees kidnapped and citizens murdered and we don;t even sanction those countries for fear of interrupting our trade with them.
As for firing on our aircraft - come on be serious. We have been told that they have been firing on our aircraft for 12 years and they have not hit one except a low flying drone, once. We are bombing their country for crying out loud. Citizens are dying over there. I don't think firing on planes over there is a threat to our national security, especially when they couldn't hit one if their life depended on it and it does.
