It's a fun story. I heard about the teams going there to raise the flag but didn't know about the whiskey.
In any case, I'd say the land truly belongs to Greenland so both Canada and Denmark are considered colonialists in my book... (even if it's hard to see the real value of a small, cold rock)
I have long read about this tradition to raise the flag :) however, I am glad that this conflict is developing peacefully.
