It's one thing when Karen Taylor-Greene want to send our military into Mexico, but Graham should know better.  MTG wants to bomb the cartels, but never explained why Mexico would not look at that as an act of war.

Over hundred years ago Woodrow Wilson sent American troops under the command of General John Pershing into Mexico to capture of kill Poncho Villa. That could have created a serious world problem had we went to war against Mexico about the same time WWI was getting started. 

I'm all for stopping illegal drugs from entering the U.S. but it's still a "supply and demand" issue. Don't have a solution to stop our dopers from buying fentanyl from Mexican dealers, but starting a war with Mexico won't stop them.
