English does use a phonetic script. The letters represent phonemes and carry no semantic meaning on their own, as opposed to an ideographic or logographic script. That fact that one symbol can possibly represent multiple phonemes doesn't make it not a phonetic script.
There's no debate about it, unless you want to debate what makes a script "phonetic" in the first place.
