Much more of these cursed alliances will happen in future unless the left and/or socially progressive forces in the west develop a coherent anti imperialist stance. As in anti NATO, anti IMF, anti World Bank. Traditional left wing positions based on global historical materialism.
Until that happens, the right wing and/or social conservatives, like the AfD here, will steal their lunch from them and form these kind of alliances. The primary contradiction globally is the disparity of living standards and wealth between the west/imperial core/triad, and the third world/global south, orchestrated by modern day imperialism and neocolonialism. Countries in the global south are prepared to work with anyone willing to end that, or at least show some support for ending it.
In short, the left in the west needs to get it's stuff together, actually practice internationalism, and actually practice anti imperialism instead of selling out to the biggest institutions of modern day imperialism on the planet, such as NATO. If the left does not do this, alliances like this will continue to happen as the right occupies, or pretends to occupy, a space the left should be occupying.
