The claims in the OP are not at all supported by reading the linked alert from DHS. This is a great example of how misleading claims are spread.
What the press release actually means, in terms of media optics
1)
DHS is justifying it's expenditures and current budget, and like all government bureaucracies, is trying to sell the narrative that it needs more "reach", more budget, more personnel, more resources and more overall power. The end goal of any established bureaucracy is to perpetuate itself first and foremost.
2)
DHS wants to distance itself from this current administrations and current Party apparatus' lean towards Anti-Semetism and Afghanistan failure by mixing it in a cloud of other factors they barely care about at all. While the "left" currently controls Big Finance, there are massive fractures in place because of the many Anti-Semetic leanings and statements and actions of major players from that side of the aisle. You can't win states ( and their natural electoral votes) without taking the big cities, and you can't take big cities until you have a strangle hold at how "governance" is applied at the smaller local level. People are attuned to what happens around the country but they are driven and motivated mostly by what they see in their day to day lives. You see that impact in Virginia. No matter people's views of large scale political topics, they believed their children were under formal and structured attack by bad faith actors in terms of elected officials and and a school system that had proven to fail them again and again.
Pushback against identity politics won't be the final nail in the coffin for the woke radical left, it's going to be coming in two directions
A) Increased aggression towards Elon Musk is idiotic.
He is critical to national security and is thus beloved by the military industrial complex. His flaws will be written off by the masses as the "quirks of genius" just like Belichick is seen as so committed and driven to win that his run roughshod style is tolerated. Opposing the military industrial complex and it's logical step brother, the various intelligence agencies, is like running into a wheat thresher. How did that work out for JFK and Princess Diana?
Media Optics 101 - See who you can't criticize, that's who has real power.
B) You can't go to war with America's Jewish establishment and win.
You need big money from major players to buy people off, leverage people, purchase votes, ballot harvest, pay for marketing and win elections. Doing so will lose you a major cross section of Hollywood ( which is the most effective propaganda tool for the masses) and major areas of Big Finance and Big Tech. You can't have situations like Jamal Bowman in New York, where he tries to kiss the ring of the Jewish establishment on one hand and keep lock step with Ilhan Omar, another Squad member, with the other and hold critical seats.
3)
Major players at DHS are expected the 2022 Mid Terms and the 2024 general cycle to go for the GOP. They are desperately trying to save their careers at the top of the food chain. You can't blame tactical commanders for following orders. However strategic commanders will either be told to fall on their swords or be thrown on top of them. Someone needs to pay for Afghanistan. Someone needs to pay for the failures of law and order all across American now. Someone needs to pay for the swinging gate at the Southern Border. Someone will say that's public policy above the paygrade of some of these people. That's just too bad. Some people at DHS were put into impossible situations and there were often no wins possible. But still blame needs to be assigned. Just like on a chessboard, pawns get killed first.
The current Democratic Party, up and down the ticket, have likely lost the military vote for the next five general cycles. And do you think the majority of law enforcement in America is so favorable to the Democratic Party right now? Endless rioting and looting driven by cooked political agendas in Big Blue Cities, Defund The Police and being smeared as a bunch of psychopaths looking to randomly execute any black people they see on the streets? Thus our national "Praetorian Guard" will shift with the winds.
4)
DHS needs a front door and back door counter narrative to the disaster in Afghanistan. And I'm not just talking about babies being tossed in razor wire and 19 million women and little girls being gang raped and sodomized as the spoils of war. Biden's "withdrawal" from Afghanistan just gave billions of dollars ( paid by your tax dollars and my tax dollars and the future tax dollars of your children and grandchildren) in high end weaponry to terrorists.
We are talking about hardware and resources that will be used to kill Americans and our allies and innocents for generations to come. DHS needs to get in front of the eventual fallout of all this. Eventually someone somewhere is going to be hit with those weapons and resources and it's going to be a story that no one will be able to spin control and it won't go away. DHS needs to say they did something and "it's not our fault, we tried to prepare but the blame should go here to X and here to Y and here to Z"
Joe Biden ( well Susan Rice as proxy for Barack Obama) gave our natural enemies the weapons to murder your children. And he made you pay for it. And he made your children pay for it. And Jen Psaki is sent out to gas light you to demand you thank them for it.
Everyone has their free speech and everyone has their right to their viewpoint, I won't take that from anyone. But I have no rational understanding how anyone who is a parent in this country could support this current administration. Jacking up the economy even further, screwing up the pandemic response, destroying the lives of countless small business owners who were burned and looted out, trying to make pariahs out of our law enforcement community, allowing countless career criminals into our country and past our Southern Border unchecked, arming terrorists with our tax dollars, cooking our educational system, showing weakness to our global large scale threats like China, taking away law and order in major cities and denying functional governance to push cheap intersectional identity politics.
"But Trump" is just not going to cut it here. But that's the opinion of the woke radical left here and it's their right to have it.
Here's my opinion -
The radical leftists here got on their hands and knees, gave up their freedom, their safety, their economic stability, emptied their wallets and begged for their children to be cannon fodder. And they peacock around like they just won the Power Ball because "at least Trump is gone"
IS THIS THE KIND OF WORLD YOU WANT YOUR CHILDREN TO INHERIT?
Cheap woke pedantic low information voters with paper thin critical thinking abilities enraged like human sock puppets by cooked shock marketing social media clickbait outrage instead of realizing they are begging for their children to die.
The real "terrorism" is the casual indifference to the clear and present threat point to all our children. Some of you just don't care as long your "tribe" wins or looks like they win. OK, you chose that. And your children will eventually pick up the tab for it in blood.
