Ways to citizenship

Hi!
Is there any, and i mean ANY ways to get the U.S. citizenship in say 1-2 years?
Reason i am interested in the fastest track to citizenship is that i am a citizen of an EU country but hoping to apply to U.S. Naval Academy. As known, all service schools require American citizenship from the applicants to be eligible. Since we graduate high school at the age of 18-19, unlike the Americans, who graduate about 2 years earlier, there is basically no way i could get the US. citizenship before reaching the age of 23, which is also the age limit in most of the service schools.
So, would it be better for me just to bury my dreams attending the USNA one day and serving in the Navy, or is there still a glimpse of hope?
