> Is the author seriously suggesting to view deliberate terror attacks against civilians
No. The prompt for the article is pointing out the difference in coverage & attention from the white house and press about a casualty from a US drone strike when the innocent victims were Western. Various terror attacks are mentioned, but that is not the core topic of the article.
> the same as military strikes performed against enemy combatants,
From the article: "Indeed, Obama officially re-defined the term “combatant” to mean “all military-age males in a strike zone.” In other words, as The New York Times reported in 2011, all males between 18 and (roughly) 54 killed by U.S. drones are presumed to be combatants — terrorists — “unless there is explicit intelligence posthumously proving them innocent.”"
> by people who are trying to minimize civilian casualties as far as they can?
from the article: "There are so many heinous stories of U.S. drones blowing up children and innocent adults. Obama used cruise missiles and cluster bombs to kill 14 children and 21 women in a Yemeni village (weeks after winning the Nobel Peace Prize), while a 2012 drone strike attacked a Yemeni wedding convoy and “killed 12 passengers in the vehicle, including three children and a pregnant woman.”"

In other words, your first sentence is a straw man. The comparison is not between terror attacks and military strikes, the military strikes are often not against enemy combatants (and they're almost never against high-ranking terrorists), and the attacks are not trying particularly hard to minimize civilian casualties. That you would try to make such a point, despite all evidence to the contrary, is the result of precisely the propaganda that the article is trying to pick apart.
