Your post assumes that the USN will approach within the Syrian missile envelope, which they will not.
Also, if anyone unleashes the canned sunshine, all bets are off. The American public would demand full-scale retaliation, and Oshitbag would piss himself and cry.
I think it’s the British that are most likely to be hit.
Syria can rain down missiles on their base in Cyprus.
US hits Syria, Syria hits the base in Cyprus and Tel Aviv.
If Tel Aviv is hit with chems they nuke Damascus.
Russian subs then might strike our naval assets with Sunburns loaded with 200kt loads.
This is all way beyond the abilities of a mental midget like Obama...he won’t make proper decisions.
If this evolves into WW3 Russia has more throw weight than we do. they also have a civilian defense plan and we don’t.
First use of a nuke and the world changes. Most likely will begin with an Israeli counter attack.
In a WW3 situation carriers and the like mean very little to the outcome...they are all obsolete in a major conflict.
All that counts is mobile missile launchers, subs and civil preparedness.
EMP attack on our mainland would be one of the first things to happen.
I wish Ronald Reagan were in the white house instead of the Marxist Muslim brotherhood fool.
We have no carriers in theater so my guess is we will use B-1 bombers from Al Udeid Air Base in Qatar and B-2 from the states along with ships outside 500 miles. We will need to get tankers and support aircraft in place but that should b done tonight I suspect. If we do anything else it is purposeful to have losses in my view.
