Recognize a comma splice when you see one. A comma splice, also called a run-on, occurs when a writer has connected two main clauses with a comma alone. A main clause makes a complete thought, so you should not find a wimpy comma struggling to join two such powerful clauses. The problem looks like this: Main Clause + , + Main Clause.
In the United States, the term treaty is used in a more restricted legal sense than in international law. U.S. law distinguishes what it calls treaties from congressional-executive agreements and sole-executive agreements.
No State shall enter into any treaty, alliance, or confederation; grant letters of marque and reprisal; coin money; emit bills of credit; make any thing but gold and silver a legal tender in payment of debts; pass any bill of attainder, ex post facto law, or law impairing the obligation of contracts; or grant any title of nobility.
