the president was undecided about the military strike.
submit

Explanation:

The idiom "on the fence" means being undecided or neutral about something. So when President Obama said he was on the fence about ordering a military strike, it implies he hadn't made a decision yet. The first option says he was enthusiastic (which contradicts "on the fence"), the second says he was firmly against (also contradicts), and the third says he was undecided, which matches the idiom's meaning.

Answer:

The president was undecided about the military strike.
