The USA spends more money per year on military stuff than all the other countries in the world put together.

Nah. The US spends more than any other country, but the next 19 countries (in ranking: China, UK, France, Russia, Germany, Japan, Saudi Arabia, Italy, India, South Korea, Brazil, Canada, Australia, Spain, Turkey, Israel, Greece, UAE and the Netherlands) spend USD 691.7 billion compared to the US's 668.3 (in 2008 constant USD equivalents). In terms of GDP, the US spent 4.07%, compared to 8.2% for Saudi Arabia, 5.9% for Jordan, 6.6% for Chad, a whopping 20.9% for Eritrea, and 8.5% for Georgia.

What's sad about the percentage of GDP is that countries like Eritrea and Chad should be funneling the money into betterment of their people and not into arms.
