Query regarding international transaction between governments 
$USD, electronic or otherwise, are not created/destroyed during international transactions. If India wants to buy an F-16s, at cost $34M USD, they'll have to actually acquire $34M USD, or else convince the seller to agree to a different currency. They would acquire that $34M USD in a few possible ways. One of which is to exchange INR (India Rupees) at whatever the current exchange rate is, to whomever will agree to the opposite - i.e., someone who has USD and wants INR, or at least is willing to be the middleman. Another would be to sell some goods or services in the US (for USD), or to someone else for USD.  Indian companies undoubtedly do this all the time. Think of all of those H1B workers that are in the news right now; they're all earning USD and then converting those to INRs.  So the Indian government can just buy their USD for INR, directly or more likely indirectly (through a currency exchange market). A third method would be to use some of their currency stores. Most countries have significant reserves of various foreign currencies on hand, for two reasons: one to simplify transactions like this one, and also to stabilize the value of their own currency. A less stable currency can be stabilized simply by the central bank of that country owning USD, EUR, Pounds Sterling, or similar stable-value currencies. The process for an individual would be essentially the same, though the third method would be less likely available (most individuals don't have millions in cash on hand from different currencies - although certainly some would).  No government gets involved (except for taxes or whatnot), it's just a matter of buying USD in exchange for INRs or for goods or services.
