If what you are asking boils down to, 'why are there ongoing wars in the world?' along with, 'who is to blame for the onging wars in the world?'. Then the answers are really not that difficult to discover.
Wars make money. So follow the money. Where does all the money end up? Why - in a bank of course. So are the banks to blame? Yes - along with their political stooges who could not get elected without the connivance of the banks and who, also, formulate policy at the behest of the banks. (NB: I'm talking big banks: like the IMF, Federal Reserve and Bank of England, here - not your local highstreet variety.)
Now you should be asking, 'why are food prices rising so dramatically all over the world?'. Simple - the banks are buying up all the food stocks and food futures (crops that haven't even been planted yet) and deliberately creating shortages. This will destabilize entire geo-political regions - with food riots breaking out all over the place - and lead to more wars.
More wars = more money for the banks.
