Trump has been threatening to close the border for months, make it harder to get asylum, and of course stop illegal immigration with his wall but he hasn't done any of those things. The only thing he's doings is encouraging migrants to come to the US while they can still get in. If he really wanted to solve his immigration crisis, he would keep his mouth shut and let his actions speech for themselves.
Threatening to close the border, etc. is not a "lie," and your your criticism of his (in)actions is self-contradictory. Want to try again?
I agree with Flopper. Don't warn them...just do it. He is encouraging more peopke to come right away so they can still get in. Like telling the enemy of war plans.
In 2016, there were no caravans of any size and apprehensions at the border were low. In Trump's first year in office, the boarder was relatively quite. There were only 2 caravans with 350 migrants. Apprehensions were the lowest in 20 years.
Then Trump began his campaign to build his impenetrable border wall followed by threats of closing the border. Meanwhile, crops in Central American were failing and economic conditions were the worst they had been in a decade. Trump began talking about cutting aid to Central American, which guaranteed to make the situation even worse. Gang activity was making most the towns in the Northern Triangle unsafe, day or night.
Pueblo Sin Fronteras, the largest of the Caravan organizers spread the word throughout Central America that Trump was closing the border and building a wall that could not be crossed. It became a now or never event for those hoping to escape. Trump got exactly what he wanted, a crisis at the border.
Trump has now put a tariff on Mexican imports to force Mexico to stop migrants. Of course Mexico is doing nothing because with summer, temperatures will rise making crossing Mexico and the the northern deserts unsafe so this year as every year, the flow of migrants north will drop. That will give Trump the opportunity to claim a victory for his policy. I expect Trump will announce he's dropping the Mexican tariffs, just in time for the election season.
