Which nation declared war on sardina in the spring of 1859 and opened the door for the unification of italy?

i think its provide for the common defense

the big stick policy was to still look powerful, and be nice at the same time. the big stick policy was also to countries who were at war, find peace with eachother.

the dollar diplomacy was to expand american business and get it to latin america, for that would be good for the economy.

you my friend, your regards.
