The blame lays with people who started and maintained a war we shouldn't be involved in. The failure is not in failing to achieve success. It's in understanding what prioritizes dictate what is worth pursuing. If you decide to be an astronaut by the end of next week, and you don't show up to your job trying to dedicate yourself to your goal, and by the end of the week you're not an astronaut, the mistake isn't that you suck and couldn't achieve your goal. It's that you were irresponsible and pursued something you should have never pursued in the first place.
