"The soldier arrives, passport control says there's a problem with his passport, asks him to step into an office while they check their paperwork and an island detective then cuffs him and escorts him on the next flight to Barcelona."
Theoretically, maybe. In actuality, not a chance. Liberals and US haters are good at finding activist judges who will pull crap like issuing an arrest warrant like this. Spain's govenment might do some political posturing, but neither Spain, nor some little Caribian country is going to abduct a US citizen under the guise of a criminal trial for an incident that has already been reviewed by the US military.
That would likely be considered an act of war.
Exactly. Did'nt spain learn its lesson last time when we were a much weaker nation a.k.a. the Spanish/American war. The tank commander probably thought they were being aimed at with an Anti-Tank missle or rpg and took a counter measure attack to eliminate the threat. I dont blame the soldiers its your life or the enemies in a hot zone, only idiots would think otherwise.
Probably should be considered an act of war, but absolutely no chance whatsoever that it would be. No chance at all.
