Everything is related.
No, it's not, but it's easier to peddle conspiracy theories and reinforce paranoia if you assume that it is.
3. Multinational corporations are able to set up shop in countries that don't nationalize industry, thus enabling them to take advantage of lower production costs and also avoid higher US taxes. Again, when a country plays by other rules such as Cuba, Iran, or Venezuela, there is no benefit to the multi-national corporation and the MIC is used to encourage the country to play ball. This involves propaganda, color revolutions, sanctions, etc.
One observation is that the economy isn't so much supporting the military as the military is supporting the economy.
You mentioned that the defense isn't an extraordinary high percentage of the budget. The budget was $3.9 trillion. A better metric is what percentage of the revenue is defense spending.
In 2016 revenue coming in was $3.3 trillion (Link). Military spending was shown at $620 billion (link). That's approximately one out every five dollars of revenue.
The ratio is one of every six dollars when compared to budget ($3.9 trillion) rather than revenue, because the budget includes money we don't have (borrowed money).
The point that you're now trying to divert attention from is that you think our military spending is "blowing up" the national debt and "draining our resources," and that's just way overblown. Sure, we can look at defense as a percentage of revenue if that's what you want to look at. However, you may want to at least start accurately citing your own source. Furthermore, you should look at a consistent source rather than scouring the internet for random pie charts.
In 2016, we spent $593B on national defense and took in $3.268T. That's 18.1 percent of revenue. In 1996, it was 19.7 percent. In 1986 when we were kicking your ***, it was 35.5 percent. In 1976, it was 30 percent. In 1966, it was 44.4 percent. In 1956, it was 57 percent. In 1946, it was 109 percent, and that was down from an astounding 278 percent in 1943, which happened for obvious reasons.
So is the military getting harder for us to afford or easier? It's getting easier whether we're talking about GDP, spending, or revenue, and it's not what's really straining our budget or "blowing up our national debt." Furthermore, the overwhelming majority of that military spending isn't spent overseas as you seem to think, and only about $10B per year is actually unique to overseas stationing. Link. It's spent in the United States.
Besides, if you think the military is supporting the economy rather than the other way around, then why the hell would the US cut its military? If what you're saying is true, that's about the dumbest thing we could do. But of course, if the real agenda isn't concerned with the US economy but with promoting and enabling Russian interests, then it makes all the sense in the world.
