There is a Composite Index of National Capability that measures the power of each country by total population, urban population, iron/steel production, energy consumption, military expenditure, and military personnel. Although many would argue this is not an accurate process, myself included, the least powerful ranking is tied with Nauru and Tuvalu, with a score of 0.

If you're asking what is the most powerful country, then the answer is the United States without a doubt. The US is the world's only superpower and has the most powerful army as well as the largest economy. If you're asking what country is the best country, then there's really no way to decide. Most will determine the #1 country by development ratings, in which the answer would be Norway. However, some people determine it by power, in which the answer would be the US. The answer could very well be the US as it is one of the most developed and least corrupt nations in the world, in addition to being the most powerful.
