Well we didn't get any help from Mexico on this war --- American citizens are to go to Iraq and die and meanwhile any jobs they could have had will be given to foreign citizens who are not expected to fight that war.
This is a non sequitor ... involvement in Iraq and illegal immigration are separate issues.
We've had illegal immigration for decades now, and
it will be an issue whether we win the war or terror or not.
There are 130 million jobs in America, all but a few million of them filled by legal American citizens and legal immigrants.
Thus ... "any jobs they could have had will be given to foreign citizens who are not expected to fight that war." ... is specious. We have a strong economy with low unemployment. Plenty of opportunities for Americans, with or without the challenge of illegal immigration.
And another point: You may not be aware, but some of the soldiers fighting for USA are *not* citizens, but immigrants.
During the Civil War the Irish went straight from the boat to the Infantry. Maybe we could just get them as they cross the border and send them straight to Iraq, gun in hand.
