Answer :
Hi. I think there are lacking details such as choices in your question but let me go ahead and try to answer this. So far, there are about seven hundred to eight hundred military bases worldwide and this is according to International Network for the Abolition of Foreign Policies. So far there are United States military bases in about 150 countries. The only countries that I can think of that has no US military base are: China, North Korea, Pakistan and Saudi Arabia.
