Bad manners or bad politics?

Ariz. Governor Orders Troops to Border By JACQUES BILLEAUD, Associated Press Writer Wed Mar 8, 10:38 PM ET
PHOENIX - Gov. Janet Napolitano on Wednesday ordered more National Guardsmen posted at the Mexican border to help stop illegal immigrants and curb related crimes. [Yahoo News]

Quoth the Governor "They are not there to militarize the border. We are not at war with Mexico."

Excuse me Madam Governor, but is it not considered bad manners to station troops along a friendly border? It really does seem like the State of Arizona is declaring war on Mexico. Now, there is the issue of illegal immigration that everyone is so suddenly up in arms about. Undeclared immigration is one of the founding tenants of the United States (OK, so it maybe one of those undocumented ones), but there are key economic jobs that are being filled by these workers (besides flipping burgers) and unless the United States wants to build a trench between itself and its neighbours, cut off all trade, access routes and airspace, undocumented illegal workers will get in. And they will not all be coming from Mexico.
