As I mentioned previously there is no instruction or admonishment for Christians to not participate in governmental affairs in the bible.
There have many devout practicing Christians and other religious denominations who do or have been involved in politics.
This forced separation from participating in world governmental affairs is not unique to JWS there are many religoius organizations who have the same doctrinal enforcement.
It becomes a bit ironic and hypocritical when these groups (JWS) take money from these governments from established worked upon social assistance programs.
These religoius groups seem to overlook matters when it concerns money.
