How is the INF dead? Trump announced he is withdrawing the US from it but he has no authority to do so unilaterally and requires the approval of the Senate to actually withdraw.

It's just being used to strongarm Russia into complying with the treaty after they violated it at least once (that I am aware of, anyway)
