No they just don't want to play troll with you. You don't even care about the question you asked.
Classic answer.
If someone asks a difficult question you don't want to answer, just call them a troll.
In other words - there have been NO actions to defend America but loads of invasions, terrorist attacks and so on.
None were to defend the United states.
Actions, invasions? Funny I thought the question was 'Should U.S. soldiers be armed?' Hmm yes that is exactly what the title says. Then I said you don't care about the question. You insult me then prove my point by ignoring it and going back on a hate America rant.
