The word "WHAC" is a slang term used to refer to the Western Hemisphere Affairs Committee. Its spelling can be confusing for non-native English speakers, as it does not follow traditional phonetic spelling rules. In IPA, the pronunciation of "WHAC" is /wæk/, with the "W" being pronounced as the sound "wuh" and the "H" being silent. The "AC" is pronounced as the sound "ack", much like the end of the word "back".
