I was able to look at the source document that Kim and Mike are presenting in their video and it in no way supports the idea that the WTBTS support the Nazi war machine.
Kim and Mike's claims in this instance are not supported by any proof.
The page that they are using to support this claim comes from a report titled Research Findings About Ford-Werke under the Nazi Regime. The form can be found at page 122 and is headed Appendix A . Appendix A is list of Investment of U.S. Companies in Germany, 1943 .

This is what the report has to say about Appendix A
At the start of World War II, 250 American firms owned more than $450 million in assets in Germany. Ten of those firms owned 58.5 percent of the total. Ranked 16th by investment holdings, Ford held 1.9 percent of the total American investment. A chart showing the top 59 firms is attached as Appendix A, Investment of U.S. Companies in Germany, 1943.
Therefore the form that Kim and Mike are using as some sort of proof about investing or financially supporting the War does no such thing. The form shows how much the WTBTS had in Assets in Germany during the war, and that's it. The amount was $596,576. That amount would have been the value of all their buildings in Germany, their printing machinery and all other assets, including money held in bank accounts.
