Wouldn't America and the world be a better place if Ron Paul was president?

No more wars, financial aid, policing of the world, withdrawal from Iraq and Afghanistan effective immediately, withdrawal from the United Nations, complete isolation from the rest of the world's politics. We will only spend the tax-dollars of Americans in a war that is in the best interest of our national protection, just as our forefathers envisioned. Wouldn't America and the world by that extension be a better place under a true libertarian and freedom fighter such as Ron Paul?
