57. affording strategic proximity to the strait of Gibraltar, Morocco was also of interest to the French(omitted) throughout the first half of th twentieth century because they assumed that if they did not hold it, their grip on Algeria was always insecure.

so “they” refers to The French. I think

my Question is:

(E) never would their grip on Algeria be secure they did not hold it 倒装的不好，ETS说awkward and confusing, but why?如果要倒装，应该是怎样的呢？谢谢
