This is a win for them, because they get to do something they already want (more cops to target migrants and Indigenous people under the guise of “security”) and now they even get to say that this thing they already wanted is absolutely definitely worth the money and really quite a “cheap” tradeoff to stop big bad America’s unreasonable tariffs.
Increased border security and larger military/police budgets is just standard operating procedure.
