They would not need to shut down all air travel - just the US flights, and US people.Because unless you shut down all air travel - the two countries are not isolated.
The smart money, looking down the road, sees a distinct likelihood that the US will be quarantined by the countries that do get the virus under control. How else could they defend themselves? It's routine, especially when dealing with substandard health care and incompetent handling of a plague, to isolate particular countries until they get a better grip - the African sources of Ebola threat were isolated like that, for example.
Any US person they actually need could easily be quarantined for two weeks on arrival, and tested for infection before release into Australian society.
I'll take that bet.Yeah, that will last about a week. Then some important Australian will insist on coming back with his American family and that will all go right out the window.
It's not impossible to have representative government that acts in the interest of its ordinary citizen - I've seen it. The US used to have something like that, and it was improving.
They prefer a clueless, planless, incompetent government at all times of crisis except the ones directly affecting their property. Nobody really knows why.If you want to chat with strangers it's going to depend on whether they want to chat with stranger at this time. I has nothing to go with any grand government plan.
I saw a guy like that a few weeks ago in a chemotherapy infusion center, after the governor of Minnesota gave notice that he was going to shut down parts of the State and forbid gatherings of people - he also recommended that people wear facemasks in public, but could not require it because lots of people could not obtain such masks.
He was sitting in a chair in a room with at least a dozen immune-compromised people and a like number of nurses, infusion aids, and other vulnerable medical personnel, all masked except him, deliberately and proudly (no kidding) coughing sort of half into his elbow as he waited for one of those infusion aids to deliver the treatment that was saving his life. And they did, as far as I know - they actually cared for him, just as they would a decent human being.
Maybe we'll get lucky, and the folks who think like that will just hang out with each other. We could do with fewer of them, to be blunt. If they promise to avoid me and my family and neighborhood, I might even foot the bill for the keg party. Free beer for the short bus.
