What are the advantages and disadvantages of nationalism and military preparedness first one to answer will get 15pts

I think that one advantage of nationalism is the unity it

builds among people who share the same nation, who start to think

of each other as co-citizens.  

One disadvantage of nationalism, of course, is the hate that can

be directed against outsiders - hate that sometimes culminates in  war.

his pledge was:

“it is my earnest desire to know the will of the providence.”

lincoln also had hatred for people who condoned and practiced slavery and so he pledged:

""and if i can learnt what it is i can do it"" this is another pledge by abraham to reassure the congregation on how to deal with the providence will.
