Harsha Walia disrupts easy explanations for the migrant and refugee crises, instead showing them to be the inevitable outcomes of the conquest, capitalist globalization, and climate change that are generating mass dispossession worldwide. Border and Rule explores a number of seemingly disparate global geographies with shared logics of border rule that displace, immobilize, criminalize, exploit, and expel migrants and refugees. With her keen ability to connect the dots, Walia demonstrates how borders divide the international working class and consolidate imperial, capitalist, and racist nationalist rule.

Illuminating the brutal mechanics of state formation, Walia exposes US border policy as a product of violent territorial expansion, settler-colonialism, enslavement, and gendered racial ideology. Further, she compellingly details how "Fortress Europe" and "White Australia" are using immigration diplomacy and externalized borders to maintain a colonial present, how temporary labor migration in the Arab Gulf states and Canada is central to citizenship regulation and labor control, and how racial violence is escalating deadly nationalism in the US, Israel, India, the Philippines, Brazil, and across Europe, while producing a disaster of statelessness for millions elsewhere.
