You would think that the United States of America was preparing for an invasion. Over 1,600 troops are being moved to the U.S.-Mexico border within the coming weeks. To increase border security, which was one of the many promises Trump made during his 2016 campaign, he has decided to use part of the military’s $700 billion budget and his powers as Commander-in-Chief to make the move.

Instead of attempting to pass new legislation or signing an executive order, Trump moved to use the National Guard because he has complete control over them “in times of insurrection.” He argues that right now is a “time of insurrection” because of the number of immigrants that illegally cross the US’ border.

Although people continue to cross our border illegally, the movement of the National Guard to the border will be ineffective and a waste of our military’s budget. However, the governors from New Mexico, Arizona, and Texas have all agreed to follow President Trump’s request, and after over two weeks of delay, the governor of California has reluctantly agreed as well.

One reason why the movement of the National Guard will be ineffective is because over half of undocumented immigrants in the United States came into the country legally with a visa and simply overstayed their visas. Only 40% of illegal immigrants are in the category Entered Without Inspection (EWI), and yet this is the only group of illegal immigration being addressed by the new move. This statistic of 40% EWIs is also a decline from a substantial 63% in 2004.

In addition, the troops being sent to the Mexican border will not carry guns or be able to make arrests according to the Pentagon. The main purpose of the troops is to “observe and report activity along the border.” This seems controversial because Trump stated through tweets that he was sending the military to guard the border due to a caravan of Central American migrants heading towards the border.

The price that the American taxpayer will pay for this attempt to stop 40% of illegal immigrants has not been disclosed by the government yet, but a similar operation conducted in 2014 with 1,000 troops cost $63 million. If the cost of the new operation is the same troop-for-troop, then it can be expected to cost around $100 million. Although $100 million does not seem like much out of our massive defense budget, it could be reallocated to another division that needs the funds more desperately.
