Hmm. "Hauling" inferrs some cooperation on the part of the cargo, and those origionally posessing it..
A similar thread involving the "arrest" of GWB by Mexican troops was amusing.. Seems were that to happen, we'd have to posess a certian central american country again..
Consider the ramifacations.. A U.S. president, soldier, or national is siezed, without due process by foreign troops.. This is known as abduction, or kidnapping by most reasonably educated persons..
Dependent upon the administration at the time of the crime, one could expect anything from a bit of whining, (Clinton) to a possible full out invasion, posession, and control of said country, and repatriation of siezed U.S. Citizens.(Theodore Roosevelt..)
Also, imagine the dismay countries such as those dependent upon U.S. aid would experience, if the U.S. in a fit of revenge told the U.N. to "Pack Sand" and withdrew funding.. One might see Canada, England, and a few other NATO countries not only protesting this "arrest" but going so far as to sever diplomatic relations with countries involved. Money talks, Bullshit walks.
Last consideration is regarding the location of the U.N.itself..
Regardless of what diplomatic immunity may represent, that building is still upon United States territory. I doubt even the most jaded NYPD, FBI, or other policing agency would fire upon a large group of American citizens demanding the release of an illegally held citizen. Were foreign troops to be used for this, war would likely ensue.
Regardless of how Clinton, and others have seemingly emasculated this nation, we still seem to be the arsenal of democracy..Pissing upon the keeper of the arsenal is hardly wise..
