It would have been unthinkable that an international agreement could prevent the United States from managing its own economic affairs, but this is the new reality we face if we do not leave the agreement or negotiate a much better agreement. This Agreement shall constitute the final agreement of the Parties. This is the complete and exclusive expression of the agreement concluded by the parties on the subject matter of this agreement. All prior and simultaneous communications, negotiations and agreements between the Parties concerning the subject matter of this Agreement shall be expressly merged and replaced by this Agreement. .
