i use to be against this idea until recently when i learned about how these cartels spreading their reign of terror in the U.S.
also, because of this stupid cartels, mexico is pratically an anarchy, and my maternal grandparents couldn't go to repair their house in mexico(they were born and raised in mexico but moved the U.S. legally a year before my mom was born.) because some drug cartels was causing problems in Guadalajara(this city's airport is the closest one to their hometown)

here's some news articles about the drug cartel causing terror in the U.S.

declareing war on a massive drug cartel not a very smart idea they will always be smugling drugs into us then to cananda not much you can do to stop it and right now they are but not grab the miltary its more of then defending their borders from the drug catels makeing money but still alot will get through borders never going to stop it

Well, if they legalize drugs, the cartels will lose their power. Otherwise, the U.S. forces should stay in the U.S.

dragonclaws, if the u.s. legalized drugs, the cartel will just invest more into illegal firearms, and human trafficking idustries

This may be 8 years old but it's still kinda relevant. And I still believe that we don't need anymore wars, especially not right now.
