I don't see how you can think nuking something just "resets" it. The whole point of sanitizing probes and not introducing foreign microbes to Mars is specifically so that we keep it separate from human intervention. Once you introduce a microbe, there's no coming back. Nuking it isn't a solution and "move fast and break things" is extremely irresponsible and ignorant when it comes to things like ecology and geography.
