And Scotty is working to pump up his foreign policy cred (from the hilarious Hunter at kos):

…prepare yourself for a chain of meaningless cliches so vapid the network had to duct-tape Walker to the chair to keep him from floating away.

[Scott Walker]: “Aggressively, we need to take the fight to ISIS and any other radical Islamic terrorists around the world… I think we need to have an aggressive strategy anywhere around the world.”
[ABC News host Martha Raddatz]: “But what does that mean? I don’t know what ‘aggressive strategy’ means.”

Walker: “Ultimately, we have to be prepared to put boots on the ground, if that’s what it takes.”

Raddatz: “U.S. boots on the ground in Syria?”

Walker: “Well, I don’t think that’s an immediate plan.”

Walker is in a bit of a tight spot here, because he has exactly zero foreign policy expertise or experience or even past professed interest; his most striking military victories have titles like the Battle of Singing Protesters vs. The Statehouse Lawn. There is little indication he could find Syria on a map, and his proposal of “boots on the ground” seems suspiciously like a phrase he read off a placemat.
