northcom, in the relations with canada and mexico -- and i realize we're talking sovereign nations versus states if we send forces it's imperative that we put it -- if canada sent forces to the united states it's possible they would put those forces under the tactical control of the u.s. commander. it doesn't mean you've given up authority. you could recall those forces and higher levels of control continue to exist. you mention the national guard. when we deploy national guard forces to other states, which is a similar parallel, i've done this this year alone from wisconsin to both north dakota for the floods and kentucky for the ice storm, i give tactical control those guardsmen who, in fact, become state assets for the states to which we deploy them. and i certainly reserve the right or governor doyle reserves the right to recall them if needed. but i think from a unity of command, unity of effort point of view, the best thing to do unless and until the federal government needs to take command for the emergency being so drastic, so severe in which case we'd all get behind the president
