- specifically allowed under Article 51;
- authorized by the Security Council; and
- permitted by constitutional and US statute law provisions.
Three General Assembly resolutions prohibit non-consensual belligerence:
- the 1965 Declaration on the Inadmissibility of Intervention in the Domestic Affairs of States and the Protection of Their Independence and Sovereignty;
- the 1970 Declaration on Principles of International Law Concerning Friendly Relations and Cooperation among States in Accordance with the Charter of the United Nations; and
- the 1974 Definition of Aggression.
Nuremberg Tribunal's Justice Robert Jackson called aggressive war "the supreme international crime against peace." Guilty Nazi war criminals were hanged.
The Constitution's Article 1, Section 8 lets Congress alone declare war. December 8, 1941 was the last time. Subsequent wars were illegal. Responsible officials were and are war criminals.
The 1973 War Powers Resolution (WPR) limits presidential warmaking powers. It requires consulting with Congress before authorizing troop deployments for extended periods.
Section 4(a)(1) requires presidents to inform Congress within 48 hours about deploying troops to areas of ongoing or imminent hostilities.
He must explain why they're sent, constitutional or legislative authority for doing so, estimated duration of involvement, and whatever other information Congress requests.
Section 5(b) mandates withdrawal within 60 days plus an additional 30 exit period unless Congress extends the time frame for another 30 days, declares war, or unavoidable circumstances require more time. Unlimited amounts are prohibited.
One exception applies. As commander-in-chief, presidents may introduce US forces unilaterally into conflict areas in case of a national emergency if America, its territories, possessions, or military is attacked.
Under all circumstances, Congress must be kept fully informed. It has final say. Since passage, presidents exceeded their constitutional and WPR authority.
All US wars are illegal. Congress violates its own mandate. Accountability is null and void.
