If you count threatening Mexico's president with war, then add that to the checklist...
Trump lambastes Pena Nieto in 'humiliating,' 'threatening' phone call - Business Insider Deutschland
"In an interview with the Mexican news outlet Aristegui Noticias, Estevez, who cited sources on both sides of the call, said, "It was a very offensive conversation where Trump humiliated Peņa Nieto."
"I don't need the Mexicans. I don't need Mexico," Trump reportedly told the Mexican president. "We are going to build the wall and you all are going to pay for it, like it or not."
Trump "even suggested to [Peņa Nieto] that if they are incapable of combatting [narco trafficking]
he may have to send troops to assume this task," she said."
Last time I checked, sending troops into a country uninvited was an act of war.
Crimes of War ? Act of War
"Until 1945, an act of war in the traditional, historical sense was understood to mean any act by a State that would effectively terminate the normal international law of peacetime and activate the international law of war. The decision was invariably that of the target State and was generally preceded by a statement warning that certain acts would be considered acts of war and would trigger hostilities. "
"In 1945, the United Nations Charter banned the first use of force...."
Ok, I stand corrected. It would be an "act of international terrorism" according to the law books.
