Awwww!
I see that you may have missed Donald Trump’s interview with himself. Here is a link that may help shed some light on my response.

But yes, the answer is “By doing it”.
And the reason that is the answer is because in asking “How does one identify, locate, detain (where and how?) and then, including families with children and grandchildren, ship them off to over 20 different nations using jumbo jets and ships (assuming these nations will take them in the first place) and of course, despite a guaranteed rainfall of injunctions from the federal courts aided by media and local church congregations.”, you paralyze yourself before you even start, and thus you have failed.
The journey of a thousand miles begins with the first step.
The deportation of 30-50 million illegal alien invaders begins with the first deportation.
It does not begin with 30-50 million deportations. Why? Because that is how you fail.
Why do people who oppose the deportation of the illegal alien army immediately propose an impossible scenario as soon as they start speaking?
Because their goal is to shut it down before it even gets out of the gate.
How do you walk a thousand miles at once!?
You don’t, and what a stupid question, right?
Trump said he’ll do it all in 2 years. Now do the numbers of how many deportees a day (over 16,000) that will have to be identified, located, processed, and detained while being housed and fed in government encampments, while court injunctions keep raining down. Pie-in-the-sky?
