Wow.. What complete and utter rubbish your post is. Are you seriously suggesting that we pay countries not to piss us off so we start a war with them?
Actually, your Government does that already. Unfortunately, it's not very good at it, and the outcome is usually the opposite.
Of course, it's an absurdity to say that you pay a 'country'. A country is an intellectual construct, people who treat it as a thing are usually poor thinkers. No, you pay people, not countries, and those people may be the current government, if they are willing to do your country's bidding, or the soon-to-be-government-but-currently-terrorists-and-murderers in which case its more a case of supplying arms and intel.
Yes, we were giving Afghanistan money before we invaded it.
There you go again, confusing an intellectual construct with actual people. The USG has given money to many people in Afghanistan. First, they gave money to the Taliban so they could win the cold war for you, then they didn't like the Taliban any more so they gave money to the Northern Alliance, then they realized that there was no practical way to form a government without the support of the Pashtun majority, so they resumed aid to the Taliban, but not the bad Taliban, only the good Taliban, who are no longer called the Taliban because the Taliban are now bad/terrorists/Al Qaeda/something. Strange how the people who bomb civilians are the good guys, and the ones fighting them are the terrorists. It's a mad mad world. But I digress.
Yea, there is no such thing as free health care,
Not to society, but there is for the individual.
no such thing as un-winnable wars,
That depends on your definition of 'winning'. But if you were to nuke Iraq and Afghanistan until there was not one person left alive, I guess you could call that a 'win'. Might make it hard to get the oil from Iraq though.
and no such thing as saving money while spending it on science and RnD
You have no idea what you are talking about. RnD into resource efficiency usually has a 9 month payback period, after which it is all savings. Maybe this is why your country is in so much trouble right now.
