“What possible grounds for war exists between the U.S. and Mexico?”
Better grounds than 90% of the wars we’ve gotten in to!
Invasion, state sponsored.
Many of our citizens killed every day by Mexico’s citizens.
Attempt by their citizens to overthrow our government..’rule of law’
Anarchy
Theft of US services
RECONQUISTA
....to name a few
There is no “invasion”, at least according to standard definitions of the term. Nor is it state sponsored rather dangerous individual initiative. When one’s rhetoric is over the top it stops being effective.
Desperate people are not used by states as an invading force. Invasions are by military personnel.
None of your complaints, no matter how disturbing, are acts of war. We had our chance to take over Mexico and turned it down over 160 years ago.
International gangs are the source of the crime you are complaining about. They are not all Mexican by a long shot.
“Better grounds than 90% of the wars we’ve gotten into!” By my count we have been involved in 10 wars, only one was justified?
