The WT legal entity could be dissolved, but the religion would continue. See quote from Man's Salvation book:
"What the coming in of Gog’s hordes upon the “soil of Israel” after the destruction of Babylon the Great will mean for Jehovah’s Christian witnesses, the developments on earth will then eloquently tell. It should not be surprising if the ninety-seven branches of the Watch Tower Bible and Tract Society of Pennsylvania should be shut down and even the properties thereof be expropriated by the antireligious governments. What will happen to the thousands of Kingdom Halls that Jehovah’s Christian witnesses have built around the globe in which to meet for spiritual edification, the future will disclose. State or national governments that issued charters and registrations to the various corporations that Jehovah’s witnesses use as agencies for carrying on the printing and distributing of Bibles and Bible literature could hardly be expected to recognize or authorize such corporations then. The antagonistic political governments cannot, of course, dissolve Jehovah’s Christian witnesses world wide, for these are not incorporated under the man-made laws of “Caesar” in any land."
