I’m great in China, I’m divisive in Germany, And I’ll make America great again?

A flightless bird of grey, brown and white, I'm no Happy Feet, though my color is alike. People always thought I was dumb, Yet, due to human interference I succumbed.

I am a monument frozen in time, a testament to the past. When I bleed, I raise the tide. My chilly nature holds me fast.

Shiver me timbers! I be a contraption of war, built by landlubbers and pirates alike. I fling mighty stones, or perhaps a unlucky soul, across the waves or over castle walls. What be I, ye scurvy dog?

I am a palace built for the dead, Where a crown is replaced by a stone o'er the head. A monument carved out of sorrow and pride, To honor the secrets and spirits inside.
