Republicans have played defense on immigration for so long that they’ve forgotten how to play offense. The waves of aliens, the dead children washing up on the banks of the Rio Grande, the thousands of free airline tickets for reunions with stateside relatives — all of these things are happening because left-wing control of the levers of power has been met by Republican ineptitude.

Shock and outrage at administration policies isn’t enough. The Republicans have provided no effective leadership in stopping the tsunami rolling north from Central America. But Republicans can control the issue, and the nation’s future, if they would lead.

The first step to leading is understanding what you are up against. This border crisis isn’t incompetence. It isn’t bungling.

It is a calculated effort to crash the immigration system and fundamentally transform the nation. It is an effort to accelerate demographic trends and forever alter the nation’s culture. Until the GOP comprehends the full measure of Obama’s purpose, the GOP will be trapped in a prevent defense, never moving past complaints about Obama’s incompetence.

To the Obama administration and open borders groups, the tidal wave across the border is not an accident, and it is not a crisis. It is not even limited to unaccompanied children.

There is a single simple cause behind the human tragedy at the border: Obama’s refusal to enforce the immigration laws. The steady flow became a tsunami after Obama implemented childhood amnesty (DACA) in 2012. This lawless immigration policy gave legal status to young illegal aliens by Obama edict.

But Obama’s lawless leniency went even further. The president publicly and proudly announced that he will not enforce other immigration laws. His presidential invitation spread like wildfire throughout Central and South America, and the lawless invasion grew worse.

If President Obama reversed these lawless policies, the border flood would stop. That’s precisely why he won’t reverse them. The border flood, the free airline tickets, the badgering of school districts that do not welcome the illegal aliens with open arms — all of these actions are calculated to revolutionize the demographics of the nation.

If the president reversed his lawless immigration policies, the cultural and demographic transformation of the nation would be incomplete. Texas might stay red for decades … unless.

xDoubt it? The administration is doubling down and even intends to expand amnesty by edict further this fall. There has been no backlash sufficient to reverse the plan. It’s payback time for House Republicans refusing to pass the Senate’s amnesty bill.

Let’s visit the laws and lawyering that got us into this mess.

George Bush deserves some blame. The legal vehicle for the mass child migration is an amendment added by Senator Dianne Feinstein (D-Ca.) to an anti-sex trafficking law in 2008. It forced the government to admit into the country any minors, other than Mexicans and Canadians, and reunite them with family or other guardians in the United States. President Bush signed the bill in 2008 that included Feinstein’s amendment.
