Iran, Russia and China Joint Military Exercise in Syria

I just saw on CNBC that there will be a joint military exercise with Russia, Iran and China in Syria with 90,000 troops, 400 aircraft and 900 tanks.

How is Israel suppose to take out Iran's nuclear facilities if that's the case?

Biblically, this is what is suppose to happen during the Tribulation. Israel will be overrun, leaving the 3rd Temple unharmed (Rev. 11.2). Then after the last 2300 days of the Tribulation, Jesus returns to cleanse the Temple (Dan. 8.14).
