Welcome to the Q&A Forum

Good question! Good question! The way to handle this is by using something called "Hreflang". Here is Google's documentation on it; https://support.google.com/webmasters/answer/189077?hl=en All hreflang is, is some on-page code which says "this is the US version, that is the UK version" etc. Google uses it in exactly this kind of scenario, it determines what pages should appear in what countries and avoids content duplication issues. Don't redirect the pages - that will stop users (or Google) from accessing the international variations so the hreflang won't work. All you need to handle this is hreflang. Hope that helps!

Links really need months in time to be really effective. So as long as your losing links are not that much of a value, your good.
