The U.S. Mexican Border is the greatest International National Security Threat that exists in that region today. The U.S. Military is tasked with defending the U.S. and U.S. Citizens – President Trump’s offer of military assistance to the Mexican President in regard to addressing Mexico’s drug cartels – which are a direct threat to both countries – is generous enough – and at this stage it’s up to Mexico’s President to respond in kind – but the Mexican President is seriously controlled by the Mexican drug lords so this offer may have to be more than generous if the threat continues to intensify.
