The right thing, done the wrong way. That may well be history's judgment on President Obama's plan to shield millions of immigrants from deportation.
Obama's executive action answers compelling calls to bring more order, compassion and even natural justice to a broken immigration system. Yet at the same time the president risks breaking the doctor's oath: first, do no harm.
The political system — indeed the social contract that binds America's leaders and an unhappy, anxious electorate — is already in fragile shape.
The president has spotted a real ill in the way that immigration laws function. But his proposed cure is unprecedented in its radicalism and scope. He seems set to grant legal papers to millions of foreigners, notably the parents of children who are citizens or legal residents. The reaction from opponents in Congress and the country may leave deep scars.
If congressional Republicans attempt even a fraction of what the hard right is demanding as revenge — from impeachment hearings to passing bills that defund what they call an unconstitutional "amnesty" — historians may pinpoint last week's TV address as the moment that hopes for substantial bipartisan cooperation faded, just 16 days after midterm elections that saw Republicans take the Senate and increase their majority in the House of Representatives.
Before history-writers set to work, it is worth considering how Obama decided that this was the right thing to do.
The case for action is not hard to make. Successive governments have stood by as America became home to more than 11 million illegal residents. That is a huge number in a country ruled by law, and tantamount to a "de facto amnesty" as both Republican and Democratic advocates for reform have said. Many of those foreigners arrived years ago, working hard and bringing up American children. But their families have enjoyed only provisional futures, overshadowed by the original sin of a parent or parents who arrived without the right papers. A traffic stop by police or a raid on a workplace has been enough to drag car mechanics, plumbers and waitresses into a deportation system meant to target convicted felons, recent border-crossers and threats to public safety.
Since Obama took office, more than 2 million foreigners have been removed. Every country has the right to police its borders, but those removals divided a lot of otherwise law-abiding families, punishing youngsters who had done no wrong.
