What countries impacted badly in World War 1?

World War I had a devastating impact on several countries, particularly France, Belgium, and the Ottoman Empire. France suffered extensive destruction of its infrastructure and a significant loss of life, with entire regions turned into battlefields. Belgium faced similar devastation, with cities like Ypres and Antwerp heavily damaged. The Ottoman Empire, which lost vast territories and faced internal strife, ultimately collapsed, leading to the establishment of modern-day Turkey and various nation-states in the Middle East.
