Yes to both. Being strong (financially, militarily, for instance) are what enable us to contain and deal with the likes of Ahmadinajad and Kim Ill Jong without having any sort of actual armed conflict. Force and strength are what keep the peace. When you bring that sort of power to the table; allies, negotiating power, and the ability to be part of keeping global peace is a given.
Being rich helps to do all of the above and it is what has enabled us to give, give, and give some more when disasters strike, or epidemics hit, or famines occur.
And if we were both again, I WOULD want to beat my chest (figuratively

) and be proud of our country and our democracy and our place in keeping this world safe. Why people are ashamed or want to downplay that is beyond me but to each his/her own.
