It is difficult to describe in figures the 'real' size of anything in the US economy
GDP calculations are nonsensical - M Hudson explains why - as are inflation unemployment, every statistic is bent
The Political importance of the MIC is not so important except internally to overwhelm and oppress the population - those who control the economy require an efficient PR war machine to do so - but they make their serious money elsewhere
This is why you think this barely functional war machine is important - you are a victim of the propoganda : outsiders, the Chinese the Russians Ansar Allah, the RoWS, have no such illusions
You refer to the defence industry as if this was an independent part of US industry, but you know all those big names, Raytheon Boeing etc depend on China, and RF

Break free from this propaganda see the fake for what it is
