Paying for ordered equipments is as simple as exchange of money and goods while business still goes on if assumes that you borrows back the money from the dealer.
There is no just rebels on that because it is expected that debtors must have to pay. You also cant tell if there maybe collateral in such transactions which failure to payback the debt would have the lender nothing to loose.
What I am most worried about the governments spending much monies on weapons is that the government would find all means to acquire weapons just to fight a war but could not find solution to fight human needs in cases of educations, hospitalities and creating better economy levels to suit the masses.
