Yet President Trump using his executive authority is equivalent to being a dictator. Perhaps your faith in God is more shallow than you realize, or God got this one wrong.
It is not dictatorial to defy tyranny and enforce the Constitution which is what this EO does. In the last few decades, the feds have failed in their constitutionally mandated duty to protect the U.S. from invasion (Art VI, Sec 4). (Illegal immigration and immigration of enemies is invasion.) Trump’s EO is based on that constitutional mandate and is thus not dictatorial but constitutional and pursuant also to current federal law.
