I should say so.
These countries could of been thinking the US wouldn't launch an all out nuke strike on them in retaliation.
Sure, that's a possibility but retaliation for WHAT? Which of these countries have attacked or overtly threatened to attack us?
But now they know we have specific targets and will try to minimize collatorial damage.
Again, why would we want to mention specific targets, sounds to me like we're issuing what could easily be interpreted as a threat to them.
This will be a much needed wake up call to these countries, as to the consequences of not helping eliminate terrorism and their access to WMD.
So, we should threaten them with a WMD to wake them up? Pardon moi, but this level of sabre rattling is a little much.
