It is interesting to note, that during what many call the war of "Gog and Magog" Russia, along with a coalition of middle eastern nations, Iran and Turkey to name two, will attack Jerusalem to "take a spoil". It has also come to the world's attention that Israel is sitting on probably the largest amount of natural gas that the world knows, some 10 trillion cubic feet. Russia is the largest provider of natural gas for all of Europe. So now we can see a potential motive for an attack as Ezekiel 38 says:
"To take a spoil, and to take a prey; to turn thine hand upon the desolate places that are now inhabited, and upon the people that are gathered out of the nations, which have gotten cattle and goods, that dwell in the midst of the land."
