The US anti-immigrant frenzy may be unsustainable due to its enforcement of the law and the rhetoric employed to justify it. The Trump administration has been criticized for targeting those with opposing political views and for ethnically selective enforcement. The campaign against immigrants, legal or not, has reached unprecedented levels, resembling McCarthyism in the fifties. Several US allies have issued travel warnings for their citizens planning to visit the US due to the arbitrary and inhumane treatment of immigrants. States with large immigrant populations and a history of welcoming immigrants are voicing objections to the federal overreach and xenophobia.
