Sounds like a declaration of war to me -
If it is a true report of a statement from a Mexican official then, it is a statement of such a nature that a real government would immediately protest. However, America has no real government. The so called leadership are mere interest jugglers. The so called leadership is deeply interested in taxpayer supported booze, drugs, women(or pleasure boys), fine food, pensions and the pomp and circumstance of public office. The citizens had better start thinking of intervening.
