Every day President Barack Obama seems to set some new record, and not a positive one. Now he has joined with Mexico's president in denouncing a law passed by an American state within the framework of federalism.

When last heard from, neither the president nor his attorney-general had read the law. Indeed, the president has mischaracterized what the law says on a number of occasions. This by itself is an act of irresponsibility of shocking proportions

This might be the first time in American history that a president has joined a foreign head of state in attacking a legitimately passed law applying within the United States. It is a completely inappropriate action, inconceivable coming from anyone with a sense of national pride. Can one imagine how the president of Mexico would respond to an equivalent action? Indeed, by putting the blame solely on his own country the president tries to avoid giving offense to a foreign leader--and thus any hope of solving the real problem--by giving what should be offense to his own.

But that's not all. A very major reason for the problem of illegal immigration is due to the Mexican government. After all, Mexico is the only country from which large numbers of illegal aliens are entering the United States. It does not stop them and there is evidence that the Mexican government actually encourages them.

It is strange that I've never ever seen anyone raise the question of how the Mexican government should better guard its own border to prevent tens of thousands of people effortlessly cross it in violation of Mexican law.

Yet it is due to the Mexican government's combination of weakness, incompetence, and deliberate behavior that this problem has developed in the first place. Now the problem is becoming far worse and more dangerous due to violent drug gangs from Mexico that seem to have become a state within a state.

Here's what Obama, indeed any American president should have said: If you don't like the Arizona law then control your side of the border so that people there won't feel a need for such measures.

Yet rather than demand cooperation or show his own ability to protect the border, Obama has attacked Arizona acting in desperation trying to do so. In effect, he walks around with a giant "kick me"--or rather "kick America and I won't do anything about it--sign.

These points hold true no matter what one thinks of the specific law in question. Having actually read it, however, I think it sounds quite balanced and sensible. Don't disagree unless you have read it, too.

On the broader issue of international relationships, can one imagine any truly liberal--not radical--Democratic president in U.S. history behaving this way?

If Obama won't stand up to Mexico how is he going to stand up to Iran or any other country threatening U.S. interests?

And what does it convey when Miss Oklahoma at the Miss USA contest gives a better response on this issue than the attorney-general or the president of the United States? Indeed, she showed more political courage, too, since she might well have known that her response could cost her victory in the contest.

The law, she explained, is an example of the federalism at work. States have the right to pass their own legislation and this is one of the strengths of the U.S. political system.
