> In my understanding the Obama administration expelled 2.5 million illegal immigrants under the same emergency powers now being invoked by the Trump administration
The last time the Alien Enemies Act was invoked was about two decades before Barack Obama was born.

The US hasn't had anything like open borders policies for more than a century (more precisely, since the original national origin quota system was adopted in 1921.)
It's probably easier to discuss policy in this area if the premises are something resembling facts rather than partisan propaganda fictions.
