You haven't read enough, then.
I did your research for you, and not -all- the bees are dying out. Honey Bees are having issues, which are the domesticated, bred-to-be-docile. While wild bumblebees and bats are /supposedly/ having issues as well, it's a 'supposed' thing. Not what we're here to discuss.
As for the Honey Bee farms, the supposed cause is a number of minor pesticides in the hives where the 'issues' are. The theory is a number of pesticides, when combined, are causing issues for the hive. Be it the bees abandoning it and dying off, or just flat-out death within it.
As it stands, this isn't effecting -every single bee farm in the world-. It's effecting certain ones across the world. The theory that it's certain combination's of pesticides being used is plausible, due to this.
It's really nothing to worry about, and I'm /damn/ positive the only reason you're asking is due to 'mass die offs' of animals recently.
Regardless, it's only the honey bees, AKA domesticated bees, that are having 'issues'. Not /every single bee species in the world/. THAT, would be something to lift an eyebrow over. This? Not so much.
There's no reason to really discuss the ramifications, as the scenario you've stated isn't yet plausible. Ask again when it's a world-wide mass /every single honey bee farm having die-offs/abandonment/ case, as well as every single bee species dying off as well.
But, eh. As for wars over food? I think it's only 1/3rd of all food made in a certain type that really /relies/ on these honey bee farms to be successfully produced. Sure, it'd kill business for that, but eh… alternative food sources and all.
Regardless, the percentage of die-offs have been steadily around 20-30% per year, which is not causing major issues for farmers. They're making ends meet, which is important. The source of the problem is still unknown, but I wouldn't call it a 'sign of the end times'.
PS: Einstein had nothing to say about bees. Don't ask.
