It's just the true capitalism recorrecting itself. This is mainly due to major government intervention. You'll find that there was also a recession similar to our most recent one in the 70's. You'll also find that a few years before each recession the government of the country/s responsible for the recession intervened with the free market (capitalist). They placed restrictions on the market. A few years later bam! Recession.
As for establishing a 'pattern'; it seems highly unlikely that there is any timeline for 'destruction', as I stated, recessions usually occur soon after the government placing restrictions on the market (e.g. income tax).
As for a possible war, I don't think that will happen.
