I don't know the level in dollar figures -- my arguement is simply if you can borrow it for basically nothing -- you are not nearing a collapse.
To make your argument stick however (That invading Iran will collapse the nation) -- you need to determine that figure, and explain why such an invasion will get us there.
All of this is true -- and none of it backs up your original assertion. Your argument is that invading Iran will collapse the country -- because of overspending. Nothing you state above makes the link.
I have argued on the other hand that such action would probably not be above the range of a 30% shock to oil prices -- and we have seen such prices before and survivied.
I agree in theory -- but look around -- reality is not bearing it out. Our inflation rate is not through the roof, we continue to have positive growth, the demand for dollars at 2% shows that the dollars is not in any real danger as of now as being replaced -- can all of this ultimately happen? Sure -- is it happening now? Not really.
We have a ways to go before we get to that stage -- and I just don't buy that the invasion of Iran gets us there. How much do you envision this war will cost? $2 trillion over a decade? Will $200 billion more a year sink us? That is what you are claiming?
"Shifting us into a higher gear" is not collapse. Yes we spend a ton of money -- far too much -- but we can reverse that at this point.
Possibly -- possibly not. The good thing about "delay" is that we can let the scenario play out instead of blindly jumping in.
