English says "Panama" as /ˈpænəˌmɑ/, which means there are three different sounds for "a" in the same word, and that should be proof enough that English is broken and should be rebuilt from scratch.
@carturo222 There are many more examples, but that's a good enough one. Comes (i think) partly from it being a hodge-podge of Norse, Saxon, German, French, Latin, Greek, etm.
