Now that you mention it, forceful reintegration would do more harm than good for the Federation. It may drive the Andorians into the arms of the Typhon Pact as well as any other Federation members currently sitting on the fence as well as drive off any potential members from wanting to join the Federation. I take it back. However, the Federation should still be on guard lest the Typhon Pact decide to intervene in Federation internal politics.
