Read the Constitution, it makes it clear that individual states do NOT have complete sovereignty. Read Article I, Section 10 and tell me about “sovereignty”.

Well no shit Sherlock. The entire point of a Union is to join together for a bigger benefit. Part of joining that Union is ceding most of your external affairs powers to the FedGov. That's not an issue. When that state leaves the Union, none of those powers ceded are retained by the FedGov, they all return to the state. They regain complete sovereignty, unless they decide to cede those powers to a different entity (Confederacy, EU, Canada, etc).
