It just occurred to me that Israel and Russia have a common advantage.
With a global (and distinctly heterogeneous) Jewish community, Israel has supporters in most cultures, including potentially hostile ones. Therefore, if they need logistical support or double agents, the resource is there, and can blend in. The fact that one Israeli double almost became the defense minister of Syria says a lot. In a way, the US' multiculturalism allows this as well.
The Soviet Union controlled huge amounts of currently sovereign territory, and in the process deposited millions of Russian citizens throughout the 'Stans. Thus, whenever they have imperial ambitions, they can fall back on "protecting our fellow countrymen" as a one-size-fits-all casus belli.
(on further consideration, such a comparison may be, in my standard style, thoroughly tangental. Ah, well.)
