History has proven that Wars significantly improve our economy. History has also shown that we have had major?

and violent conflicts every 11 to 13 years since WWI. During the crash of 1929 companies incurred huge layoffs, unemployment skyrocketed, wages plummeted and the economy went into a tailspin. World War II seemed to be the answer and helped pull the country out of that great Depression by the early 1940s. Should we not pick a fight with Russia, Syria or Iran to get this economy back on track again? Since it is all about the almighty dollar, this seems to be the only answer. I know we could all grow gardens, raise a few pigs and trade our handicrafts to survive but I like shiny new things, don't you? New cars, new houses, lots of toys. Why not go kill some of our enemies and get things rolling around here anyway? Has this not been the nature of humanity since the beginning of time? If somebody stronger than you wants something you've got, it's expected they will come and take it right? History has proven that also, long before there was a United States. So, I think we should beat them to the punch, don't you? If not, do you have a better solution?
