Look at the “thinking” that led them to this. Woke ideas: racism, white privilege, self-loathing guilt have led to their opening of the floodgates. Same as here. Millions of soldiers admitted under Biden. The difference is we are used to dealing with them and will dispatch them if needed. Europeans are defenseless. Americans are not. We are patient to a fault, as is prudent considering the alternative, but not defenseless.
Perhaps only until the "them" you speak of owns our government.
"They" are enjoying a rapidly increasing gain of political positions and power.
Tragically, some or much of that gain is due to the efforts of domestic enemies and international adversaries.
In any event, whether future elections are riddled by fraud may well become immaterial.
The next federal election could easily become the "tipping point".
