An idealized depiction of King John placing his royal seal on the Magna Carta on the 15th of June 1215 at Runnymede. (James William Edmund Doyle - Doyle, James William Edmund (1864) "John" in A Chronicle of England: B.) See: owlcation.com
The First Barons’ War (1215–1217) was a civil war in the Kingdom of England in which a group of rebellious major landowners (barons) led by Robert Fitzwalter waged war against King John of England. The conflict resulted from King John’s disastrous wars against King Philip II of France, which led to the collapse of the Angevin Empire. And John’s subsequent refusal to accept and abide Magna Carta, which King John had SEALED on 15 June 1215. Once SEALED, a charter CANNOT be reneged without the agreement of the charter’s signatories.
An AGREEMENT is between the parties involved. In a charter, it is BINDING.
A TREATY is a FORMALLY CONCLUDED and RATIFIED agreement between states.
To later renege on an agreement is a SERIOUS act of ILL FAITH, ILL WILL, and NASTINESS. The other party or parties has/have the RIGHT to RECTIFY in whichever way it deems fit to bring about SOLACE. That is how WARS come about. That separates the good guys from the bad guys. The breaking of agreements is NOT the DONE THING.
(America’s unilateral withdrawal from the SALT (Strategic Arms Limitation Treaty) AGREEMENTS with the former Soviet Union is an example of NASTINESS. That could lead to Armageddon. The Russian Federation, which LEGALLY acquired the assets of the former communist regime, did NOT break that agreement. So, we know who the bad guy is).
