A reflection.
In early 1916, Pancho Villa raided Columbus, NM, killing
18 Americans while Villa suffered some 100 casualties.
We buried their dead while hanging those captured; then
POTUS Wilson ordered John Pershing to capture/kill Villa.
After months of search and destroy, some 3000 Mexicans
has been killed but Villa was not found.
There is ample precedent for a forceful response to Mexico's
drug scumbags.
