The US tacitly agreed to Virginia's right to secede when it accepted Virgina's ratification documents as they were written.
And there is nothing in the Constitution which expressly allows states to unilaterally withdraw from the union.
And there is nothing in the Constitution which expressly states that they can't.
The Supreme Court ruled that such a power does not exist.
Shazzam...really? The top Federal court ruled in favor of the Federal government? Whodathunkit. Let's move along now, no conflict of interest here.
The U.S. accepted nothing, it was Virginia that was doing the accepting. They accepted the powers and restrictions as outlined in the Constitution, and agreed to abide by them. The fact that they stuck extraneous wording in their ratification outlining assumptions which proved to be wrong is meaningless.
And there is nothing in the Constitution which expressly states that they can't.
No. So one looks at implied powers. If the states have the sole authority to admit new states through a vote by their members in Congress, and Congressional approval is needed for states to combine or divide or change their borders by a fraction of an inch then it stands to reason that the approval of the other states should be required for leaving the Union as well.

Haven't read the Constitution, have you?
