in theory you would have to apply for a visa, which you might just get, though your conviction was quite recent. The US embassy says you have to apply for a visa if you've been convicted, or even just arrested, for any offence.
But the actual question on the Esta form is "Have you ever been arrested or convicted for an offense or crime involving moral turpitude or a violation related to a controlled substance; or have been arrested or convicted for two or more offenses for which the aggregate sentence to confinement was five years or more?" That's more limited, as it's only about moral turpitude and drugs.
What's moral turpitude? See here:

I don't know if "malicious destruction of property" includes you. Offensive weapons don't seem to bother them.
If you do apply for a visa, it can take months to get an interview. An interviewer may think you'll still be eligible but maybe not for a few years more after your conviction (there doesn't seem to be any rule, but some people suggest five years or so).
Or you could just apply for the Esta and say "no" to the question. They don't have access to UK criminal records except, as far as I know, for big-time criminals. So you'd probably have a good chance of getting away with it.
Over to you, though.
