As countries like America continue to debate issues regarding healthcare, immigration, education, and a variety of other topics, there is a resounding feeling of division, both politically and economically. However, such a reality is mended with the implementation of a mandatory conscription. 
Such a program will bridge such divides, encouraging solidarity in the process. This is specifically executed through military training, missions, and shared goals. 
As made clear by Army veteran Tom Wolfe, "There is nothing in the civilian workforce that can approximate the bonding that occurs in the wardroom, ready room, or foxhole. Military personnel in those environments put up with much hardship— long hours, stressful working conditions, danger to personal safety, separation from loved ones, and more. However, because they all [are] in it together, they get through it." 
Thus, by creating mandatory conscription, this shared experience will be true for all. Citizens will truly understand and even develop an appreciation for the sacrifices so many have made. In turn, such camaraderie will continue into civilian life, subsequently promoting national pride and unity.
Moreover, of the thirty countries that require military service of their citizens, Switzerland is among those that have witnessed the greatest success. Similar to other countries like the United States, Switzerland is composed of numerous ethnic groups. This is significant as such differences amongst its citizens most often work against any hope of unity. Yet, the implementation of their own mandatory draft has proved successful in promoting national solidarity, altogether bridging cultural and linguistic divides.
As a result, Switzerland is identified as one of the happiest countries in the world by the United Nations.
In turn, other countries will similarly benefit.
