It is accepted that a congressional-executive agreement method is a complete alternative to a treaty method: the president can seek approval of any agreement by joint resolution of both Houses of Congress instead of by a two-thirds vote of the Senate alone. Like a treaty, such an agreement is the law of the land, superseding inconsistent state laws as well as inconsistent provisions in earlier treaties, other international agreements, or acts of Congress.

However, scholars that have written on the subject actually like this system better than just a vote in the Senate as it brings in more debate and incorporates both houses.

However, in this case, the vote to approve was ratified by a 2/3rds vote 42-21 in the Senate, so the vote in the House became a moot subject.
