I think on the whole the US’ lockdown was pretty weak and had low compliance; I think compliance was to a large extent dependent on things already looking bad enough locally to feel dangerous, at which point it’s too late to get case levels low with the duration and severity of lockdown people have been up for. (‘Compliance’ might even be the wrong word for it, since I think people were mostly just avoiding things based on how dangerous things looked to them personally, not based on any top-down rules or guidelines.)
