The war on immigrants is the same as any other war.
Governments use wars to distract from problems they have created at home. Riding on the wave of mob-hysteria created by their wars, they expand their power, wealth, and dominance.
War is the health of the state. Even if there seems to be good reasons for going to war, as in WWI & WWII, it's not worth the price we pay in lost freedom, wrecked lives, and ruined economies.
Americans fought the Revolutionary War and the War of 1812 to avoid the single-digit taxation from England. How is America's level of taxation now?
Americans fought WWI, WWII, Korea, Vietnam, and the Cold War, in order to fight the spread of Socialism, Fascism, and Communism. How is America's level of Socialism, Fascism, and Communism now? Things get worse with every war and with every election cycle.
Every war, large or small, is used as an excuse to expand the dominance of the state and shrink the rights of individuals. War is just a way to get the populace riled up and running to their masters for protection. And the Spin-Doctors keep Waggin the Dog!
Strong borders will cost billions of dollars, and those billions will go to the usual military-industrial corporations, making those corporations more dominant in US policy-making.
Those corporations already own the big media, the Pentagon, the White House, big pharma, big politicians, etc. They get money from big-government programs like the "border war", the "drug war", the "war on climate change", the "War on Terror", and so on. And then they use that money to drum up new wars and worries - false flag operations, whatever it takes, ... Whatever they think they can get away with.
I suggest We Don't Get Fooled Again.
The R's & D's play "good cop, bad cop" in a sleazy display of Political Theater, and everyone lines up to cheer their team. No matter which side you are cheering for, big government and big corporations are always the winners, while tax-payers and basic human rights are always the losers.
Better to admit that Constitutional Representative government is a failed experiment, many times over. Let's start looking for ways to dismantle the biggest, most expensive government in the known universe.
