A blog called Shock and Awe has a great post about a Marine named Jesus Angel Gonzalez, who was born in Mexico but had lived in southern California since he was seven years old. He was not a US citizen. He opposed the war, but did not desert, unlike his commander-in-chief did during Vietnam. Jesus Angel Gonzalez was killed in Iraq. an excerpt:

How ironic, but not unexpected, that this brave young man without even the ability to vote in his adopted homeland showed more patriotism and loyalty to this country than the coward who is supposedly the leader of the free world.

When a man or woman joins the U.S. military, they are making a commitment to the people of this country -- they are willing to put their lives on the line, to kill and be killed, in order to keep us safe.

As American citizens, we have a sacred responsibility which must be our response to the commitment of our soldiers: We must ensure that they do not give their lives in vain.

The decision to engage in military activity, risking the lives of our troops, is one of the gravest choices a democracy can make. For this reason, the Founders granted that ability to Congress alone, as the representatives of the people.

With this war, we have failed our duties to our troops. -- More.
