Abstract
In the aftermath of big international crises, it is customary to reassess and modify the methods
that are used in the instruction of foreign languages. The strategies used in the aftermath of
WWII and other wars demonstrate that language training has broader benefits than just
improving communication. It may help with rebuilding, increase security, and foster
reconciliation, among other things. In order to foretell the potential role of English as a foreign
language after a hypothetical third world war, this study meticulously examines historical
evidence. There are similarities between Germany, Korea, Bosnia, and Afghanistan in terms of
the development of curricula, the training of teachers, and the policies that govern the country.
Although English will remain crucial for worldwide communication, its usage may face more
scrutiny owing to cultural autonomy.
