Re: why hasn't anyone tried to assassinate Rothschild or other major central bankers?
We should not forget that those people are top Satanists and that Satan helps them, killing their enemies, warning them of danger, etc.
Of course, God allows that only because they are part of His overall plan. AntiChrist needs them to come to existence, so they will keep on for a while.
It is not up for men to destroy them. They will eventually suffer horrible deaths during the Tribulation or when Christ comes back. meanwhile, they may very well die of disease or get crazy and hang themselves, like Amschel Rothschild did.
