We need to import the vaccines and many other essential things, such as some food items, medicines, gas etc from other countries. We are not self sufficient, why don't we co-operative with others positively. It's in our own interests and theirs to and so much more can be achieved and saved.
The 'me' first approach being taken by a number of countries is edging the world towards a major conflict of which there will be a point of no return where no one wins or is worth winning, sadly we don't seem to learn from history.
Very similar to individuals who say it me and my family first and I don't care about anyone or anything else. I understand why people think like that but again the reality is we need to co-operative and support each other, we are connected and society doesn't exist in a vacuum. Retrenching and selfishness doesn't make you safer, it makes you more vulnerable and needing, more and more weapons, alarms and technology to help keep you safe.
