Motion: Unilateral US military action against cartels in Mexico would violate Mexican sovereignty.
Original claim: "Sovereignty is the ability of a country to control all territory within its internationally recognized borders."
🔴 Verdict: Inaccurate. Legal sovereignty is distinct from effective territorial control.

💬 "States are juridically equal, enjoy the same rights, and have equal capacity in their exercise. The rights of each one do not depend upon the power which it possesses to assure its exercise, but upon the simple fact of its existence as a person under international law."
Original claim: "A military incursion into another country's territory constitutes a violation of that country's sovereignty."
🟡 Verdict: Generally accurate, subject to legal exceptions. Unauthorized military incursions violate territorial sovereignty unless a valid legal basis exists.

💬 "All Members shall refrain in their international relations from the threat or use of force against the territorial integrity or political independence of any state, or in any other manner inconsistent with the Purposes of the United Nations."
📝 Conclusion: The ICJ case illustrates that security concerns alone do not establish a legal right to use force in another state's territory.
Original claim: "An incursion into another country's territory is still a violation of sovereignty even if it is justified under the laws of war."
🔴 Verdict: False as an absolute statement. A military incursion may be lawful if justified by a valid legal basis, such as self-defence under Article 51 of the UN Charter, provided the applicable requirements are met.

💬 "Nothing in the present Charter shall impair the inherent right of individual or collective self-defence if an armed attack occurs against a Member of the United Nations..."
📝 Conclusion: A cross-border military operation is not necessarily unlawful in every circumstance. Its legality depends on whether it has a valid legal basis under international law.
Original claim: "Crossing the Mexican border to counter a threat to the health and welfare of U.S. citizens can be justified."
🔴 Verdict: Legally unsubstantiated as stated. Drug trafficking may justify domestic law enforcement and cooperation with Mexico, but it does not automatically authorize military force on Mexican territory.

💬 "For all these reasons, the Court finds that the legal and factual circumstances for the exercise of a right of self-defence by Uganda against the DRC were not present."
📝 Conclusion: The Uganda–DRC case illustrates that security concerns do not automatically justify military intervention in another state's territory. Protecting public health alone does not establish a legal basis for such action.
Original claim: "Military intervention can be justified if the host country is not adequately addressing a threat originating from its territory."
🟠 Verdict: Legally disputed. The "unwilling or unable" doctrine remains controversial under international law. It argues that a state may use force against non-state actors in another country if that country is unwilling or unable to prevent threats originating from its territory. However, this doctrine has not gained universal acceptance.

💬 "The 'unwilling or unable' doctrine [...] has also sparked significant disagreement among states."
📝 Conclusion: A country's failure to address a threat originating from its territory does not automatically authorize another state to intervene militarily. Any use of force must have a valid legal basis under international law, and the legality of relying on the "unwilling or unable" doctrine remains disputed.
Original claim: "It is in the United States' self-interest to intervene militarily to protect its social, economic, political, and health interests."
🟠 Verdict: Not fully supported. Military intervention may serve some U.S. interests, but the available evidence does not establish that it would protect all the interests listed. It could also undermine security cooperation with Mexico and create additional risks.

📝 Conclusion: The claim is a strategic judgment, not an established fact. The existence of threats to U.S. interests does not prove that military intervention would protect them.
Original claim: "A country's sovereignty may end when its territory is used to prepare hostile actions against another nation."
🔴 Verdict: False as a general statement. The use of a country's territory to prepare hostile actions does not automatically terminate its sovereignty.

💬 "For all these reasons, the Court finds that the legal and factual circumstances for the exercise of a right of self-defence by Uganda against the DRC were not present."
📝 Conclusion: Although Uganda claimed that armed groups operating from Congolese territory threatened its security, the Court found that the conditions for self-defence were not met. A security threat does not automatically end a country's sovereignty.
