Certainly part of the reason!
After thinking about it, could be that the folks sending the fentanyl via Mexico plan to disable as many of the work force as they can by doing this and also causing homelessness. Supposedly there are 600,000 homeless, but I think it is a lot more. So that to my mind makes an open door for the flooding of the borders and lowering the requirements to get here. Obviously the US government is complicint in this scheme.It also is easy to take down the present form of government by sending in "troops", the 5th column. Michael Yon has warned about this for years, now it is rolling out of control apparently.
