Dunedain - I wonder if this also was part of the reason they specifically allowed Mexican Witnesses to lie about their political affiliation, and avoid jail time, but brothers in Africa had to DIE for their stance. I don't know for sure, but it wouldn't surprise me if there wasn't a monetary reason behind that too.
I'm more inclined to believe there was a monetary reason behind the GB allowing Mexican JWs to freely lie while letting Malawi JWs to freely die.
Think about this: If Mexican JWs were persecuted then they would flee and end up across the border in the US. This would then make it the GBs responsibility and the congregations burden. Every dollar a JW in the US spent on a theocratic refugee would be one less dollar to donate to Watchtower.
