“Many presidents have sacrificed American lives for the sake of foreign policy.”
Change “foreign policy’ to read “political expediency” and this sentence would be correct.
One man’s political expediency is another man’s foreign policy. Disgraceful as the Administration’s conduct was around the Benghazi attack, it won’t do in Obama or Hillary.
The real story will be in weapons smuggling, prearranged kidnapping, or perhaps murder for hire. And even if those proved true, it’s an uphill battle to make those impeachable offenses.
