I would say that demographic tensions in the US, colloquially “american racism” primarily have a particular flavour - namely focusing on skin colour. In other parts of the world demographic tensions come in many other forms. Between Europeans for instance it is more often cultural and religious tensions (secular/atheist vs religious, protestant vs catholic, germanic vs latin etc).

For each region and people these sorts of tensions tend to have a basis in different historic catalysts. In Israel for instance, there are jewish-arab tensions with a long and complicated history, interreligious tensions (christians - muslims - religious jews - secular/atheist), intra-jewish ethnic tensions (mizrahi-sephardim-ashkenazi) and many others. Similar tensions can be found in other countries in the middle east.

The problem with applying the american lens to these other areas is that it will miss important aspects and risks exacerbating problems by applying inappropriate remedies.
