This may serve as warnings for those Democrats taking "victory laps"

This article speaks to the recent Iran launch of intercontinental Ballistic Missles.

"a group of Senate Democrats responded with a letter to Secretary of State John F. Kerry denouncing Iran’s move as a violation of U.N. Security Council Resolution 1929 and calling for “unilateral and multilateral responses.”

"“There must be no ambiguity in our willingness to enforce Iran’s obligations under UN resolutions and the JCPOA,” said the Oct. 21 letter signed by 11 Democratic senators.

Only two of those — Sens. Benjamin L. Cardin of Maryland and Charles E. Schumer of New York — voted against the deal.

The episode exemplifies a worst-case scenario for Democrats as they head into next year’s election, namely that Iran will give Republicans ample “I-told-you-so” opportunities by breaking the agreement, violating other international sanctions or keeping the issue in the public eye with recurring acts of aggression or anti-U.S. rhetoric.

Only two of those voted against which means already the voting Dems are weakening.

Anyway, should be an issue for the debates between the two candidates next fall.
