If a child is born on a US Military base in Europe does he have dual citizenship?

A child born on a US Military base in Europe typically acquires US citizenship at birth due to the principle of jus soli, which grants citizenship to individuals born on US soil. However, the child's citizenship status in the host country (such as Germany or the UK) depends on that country's laws regarding citizenship by birth. Many European countries do not automatically grant citizenship to children born to foreign nationals unless specific conditions are met. Therefore, the child may have Dual Citizenship if both US and host country laws allow for it.
