Tony Tata writes at FoxNews.com about President Trump’s deployment of troops to the southern border.

President Trump was right to order troops to our border with Mexico to reinforce our overworked law enforcement officials and protect our sovereignty.

For nearly 100 years, the U.S. Border Patrol has defended our boundary with Mexico against terrorism, drug trafficking and illegal immigration – three serious threats to U.S. security.

The U.S. military and the Border Patrol have a history of working closely together.

In 1989, President George H.W. Bush deployed U.S. military forces to the border to work in concert with the Border Patrol to strengthen our defenses against increasingly problematic infiltrators. This organization was named Task Force 6, now Task Force North, and has continuously provided the U.S. Border Patrol with intelligence, support and necessary shows of force.

Those who believe the president’s deployment of troops to the border was a political stunt ignore this history – and ignore the fact that both Republican and Democratic presidents have presided over U.S. military operations along the border.

Why does President Trump now receive criticism for securing our borders? Three reasons:

First, whatever President Trump does, the left reflexively supports the opposing position. …

… Second, the progressive left no longer sees America as the beacon of hope for the rest of the world.

Instead of embracing nationalism and patriotism, leftist progressives are bent on highlighting our divisions – whether they be race, sex, religion, or any number of characteristics, as long as they can be used to sow division. …

… Third, progressives view every success achieved by President Trump as the further unraveling of President Obama’s legacy.

Troop deployments are just another sign of positive action, as opposed to the political rhetoric most politicians rely upon.
