The numbers NOBODY wants you to see. Military spend now TRIPLE that of cold war.

Inflation adjusted chart

See the following for the numbers each year :-

From this it can be seen that current military spending is now far higher than it was during the height of the cold war and the Vietnam war.

But the current numbers very significantly understate the true level of National Security spending.
The government is trying to cover up the true levels by hiding a long list of military spend in other departmental budgets.
E.G. the cost of maintaining America's nuclear arsenal, which is booked to the Department of Energy.
E.G. the increased costs of Veterans pensions and medical care that are a direct result of the wars (they are not included in the Pentagon budget).
Neither is the massive ramp up in DHS spending for domestic spying etc.

In 2011 the true level of military spending was about $930bn.
For 2012 true military spending increased VERY substantially to $1,219bn.

The REAL National Security budget - the numbers NOBODY wants you to see :-

N.B. CBO spending plans show that military spending is planned to increase every year from 2014 to 2023 - rising by well over $100bn a year from 2012 levels by 2023.
