The divide-and-conquer strategy that works so well in warfare and politics also represents the best approach for confronting the problem of millions of illegal immigrants who live and work in the USA.
No one knows the actual number of undocumented, unauthorized residents, but the best estimates suggest that they comprise more than 11 million of our neighbors. This massive segment of our population hardly represents a monolithic, homogenous group —for one thing, nearly half (44%) of illegals come from nations other than Mexico. Moreover, as many as 50% of them never ran across the border but entered the USA legally and then stayed longer than their formal authorization permitted.
This hugely diverse collection of humanity defies attempts by impassioned advocates on all sides to generalize about illegals. Anti-immigrant activists distort reality when they suggest that the undocumented are predominantly gang members, welfare chiselers and uneducated burdens on the taxpayer. Most illegals actually work hard and pay billions in taxes, while many own their own homes, go to church and give to charity.
At the same time, it's ridiculous to suggest that all illegals count as good neighbors, loving parents and inspiring examples of the work ethic. About 400,000 have run afoul of the law, with warrants out for their arrest as they defy governmental efforts at deportation.
A reflection of humanity
In short, like every other group, illegals include examples of both the worst and the best of humanity: Some of them damage our society through criminality, abuse of the social safety net and insistence on ethnic separatism, while many others toil tirelessly at their jobs while raising decent children and longing to take their place in the mainstream.
The only sensible approach is to recognize such divisions and to respond accordingly: making it difficult for the destructive immigrants to remain in the USA, while making it possible for the first time for the best, most useful of the illegals to take the path to citizenship and assimilation.
Rather than expecting governmental bureaucracies to determine who deserves to stay and who ought to leave, it makes far more sense to force illegals to choose for themselves. That was the core idea behind the immigration reform bill passed by the Senate last year, and with suitable modifications it's the same approach that deserves revival by the new Congress and approval by the president.
The choice presented to undocumented immigrants must be clear-cut: If they've avoided serious criminality, worked steadily at jobs and mastered English, they should get the chance to pay stiff fines (at least several thousand dollars) for initial unauthorized entry and to pay all back taxes in order to qualify for legal residency and begin the path to citizenship. This approach would allow the immigrant to acknowledge his wrongdoing in violating the border, and to commit himself to making up for that wrongdoing by following rules that allow him to enter the mainstream.
For those who don't choose to pay the fines and obey the new regulations, or whose past criminality or failure to learn English makes them ineligible for "earned legalization," there's only one other choice: Go home.
The vigorous enforcement of workplace sanctions against employers —combined with a vastly improved, high-tech system of ID, and aggressive efforts to serve existing warrants and deport criminals —should greatly reduce the number of illegal immigrants who neither want nor deserve to remain in the USA.
Anti-immigration extremists will protest that no illegals deserve this choice: They entered the nation without permission, and so the only response is to demand their departure. Many activists in this camp (including Pat Buchanan) acknowledge the impracticality of mass deportations but favor a policy of "attrition": making it impossible for illegals to work by enforcing strictures against employers, thereby forcing them to leave the country. The problem with this scheme is that even its most enthusiastic advocates acknowledge it won't work for most of the undocumented.

In other words, even the most militant foes of illegal immigration recognize that they will manage to expel only half of the undocumented —and the ones they'd force out largely comprise the wrong half. People who want to work hard, get educations for their children and become Americans would, for the most part, be forced to depart. Meanwhile, those who stay would disproportionately represent lawbreakers and others who manage to operate "below the radar."
Ultimately, even the most stringent effort to expel illegals will leave millions remaining in the USA, and the most important goal for this mass of humanity is assimilation —following the path of previous immigrants into the national mainstream.
At the moment, the biggest obstacle to such assimilation involves the impossibility of ever achieving legal residency. When the law makes it impossible for an immigrant to correct his illegal status, he faces greatly reduced motivation to embrace a new American identity.
That's why the only realistic policy comes down to divide and conquer: Divide the immigrants who ought to leave from those who deserve to stay, and then conquer the families who pursue legal status with the overwhelming power of the American dream that they've chosen to embrace.
