Are all these people swarming in from Mexico the victims of some sort of political persecution? Is there a famine, or some other great natural disaster, now going on in Mexico?
If either of these conditions exist, there is great justification for entering that country with a large enough military force to successfully suppress the political persecution, even if that means removal of the current government, and installing one that can restore the internal balance of the nation. If Mexico has deteriorated to the point that there is widespread social disintegration and loss of civil order, through some calamity, then they desperately NEED our help, and should get it immediately.
Of course, these foreign expeditions do cost a good deal of money, so in exchange, we would accept Mexico's kind offer to repay us with adequate supplies of crude and refined petroleum products. As part of the deal, the US corporations will be extended the right to set up domestic operations, which will employ large numbers of the Mexican native population.
In fact, it makes enormous good sense to adopt the policy of making Mexico a protectorate of the US, and annex their entire territory, giving the Mexicans the same rights as Puerto Ricans now enjoy.
Let's roll!
"In fact, it makes enormous good sense to adopt the policy of making Mexico a protectorate of the US, and annex their entire territory, giving the Mexicans the same rights as Puerto Ricans now enjoy."
Wouldn't that be blanket amnesty as well?
Puerto Rico is not merely a "protectorate". It is a territory of the United States, U.S. soil under the sovereignity of Congress and those born here are born citizens of the United States of America.
The United States of Mexico should get their act together and stop pretending that the United States of America take care of their indigent population.
