An invasion force from Central America is fast approaching our southern border. Some of the people may have ill intent to our nation, and some may just be looking for work, while others may seek asylum.
Since political correctness dictates that all are assumed to have innocent intentions, we must treat them all the same. Just like screening at all our airports, to avoid missing the one that does irreparable harm, all Americans are screened. This is no different. In order to be effective, all these individuals must be verified as to their point of origin, their destination, their contacts here, and their intentions if they are allowed to enter.
Since this influx is similar to an invasion force from another country, it must be treated as such. The border agency does not have the resources, and frankly this is above their pay grade. The United States Military, however, does have the capability to handle such things. The United States has no choice at this point, to properly address and assess these people it must be deployed, and in adequate numbers as to not be overwhelmed. If the invaders use force to gain entry, then equal and opposing force must be given to neutralize the threat.
Once the enemy surrenders and has been captured in the military operation each individual can be assessed as to the threat level and appropriate action can be taken on a case by case evaluation process. There is no other reasonable response that can be taken at this point. The invading force has grown to that of a whole battalion of forces of 14,000 strong.
DEPLOY THE ARMED FORCES AT ONCE! Failing to do so may historically, go down as the biggest blunder of the Trump Presidency, if not, any presidency.
