Mexico will never sue the U.S.!
What stautes/treaties would the cause of action be based on?
Besides, it would create a Mexican/U.S. PR nightmare!
As usual, someone's mouth moved, before the brain.
It may not be "mexico" but it could be one of their satellite anti-american organizations here in the US. MALDEF, LA RAZA, or LULAC. They have filed lots of lawsuits, including the suit that removed Prop 187 from CA.
The ACLU likes to sue on behalf of illegals too.
