The UK locked down and largely contained the virus a few months ago, then they relaxed most restrictions. This resulted in another wave and a second lockdown being imposed,
Singapore locked down for seven weeks back in April/May to contain a surging case load, restrictions were heavily enforced. The virus was largely contained and a gradual opening up was initiated. Some restrictions are still in place but apart from international travel and nightclubs things are largely back to normal, with nearly two weeks of no new local cases and around sixty current ones.
A gradual easing of restrictions and a carefully monitored, staged opening up can be safely accomplished.
