Does this Compute?

Dear President Bush,

I will share the first and last 2 sentences of a news article. Your task is to look for logical inconsistencies in the statements.

First 2 Sentences The first National Guard troops sent to assist immigration agents prepared Sunday to work on projects near a fortified stretch of desert along the U.S.-Mexico border. The new troops will be extending fences, improving gravel roads and working on border lighting.

Last 2 Sentences About 170 troops are already helping federal and state officers there with communications, fence construction and anti-drug efforts. The National Guard has been providing such assistance along the Arizona border for more than 15 years.
How can “the first” National Guard troops be sent to assist immigration agents when they have been doing the work for over 15 years? This does not bode well as our immigration problem ballooned the last decade. Why will this “new, but very old” strategy make a difference today?

Write me back, I want to know if your strategy qualifies as insanity, doing the same thing you have always done expecting a different result. Einstein said “we can’t solve problems by using the same kind of thinking we used when we created them.” How has our thinking changed over the last 15 years?
