I believe that the construction of a physical barrier between nations is in contrast with the spirit of solidarity that should exist between peoples .
Furthermore , in my opinion , this is not the solution to the problem of drug trafficking and illegal immigration .
Although the construction of an extended and fortified wall on the border with Mexico was Trump's major electoral promise , I am convinced that the estimated twenty-five billion for the wall's construction could be better used to pursue the goal of national security by other means .
For example , an alternative strategy could be to strengthen border controls with modern technological tools such as drones or collaborating with Mexico to defeat drug trafficking at its root.
This is my opinion . What's yours?
