The Laramie Boomerang correctly noted that the United States had crossed back into Mexico, but just right across the border. This was something that the US would end up doing in a worried fashion for years, showing that while the Punitive Expedition might be over, armed intervention, to a degree, in Mexico, was not.
At the same time, the press was really overemphasizing US combat action in Europe. The US wouldn't really be fighting much for weeks and weeks.
And the on again, off again, hope that the Japanese would commit to ground action was back on again.
Meanwhile, in Lander, things were getting really ugly. "German sympathizers" were being made to kiss the flag.
That probably didn't boost their loyalty any.
