The intel agencies don’t mess around... they probably have various assassination plans for just about anyone of note. The Pentagon works the same way, they have contingency plans to invade Luxembourg if need be. For my money, the Mossad is still the best. They murdered a bunch of Iranian scientists a year or so ago before anyone knew what was up. And of course, Putin... I wonder if his hand picked successor has ties to the KGB as well.
More likely Mr. Tomlinson is a self-promoting wingnut— likr the VIPs group of former bureaucrats on our side of the pond- who is trying to increase his book sales with bizaare accusations.
