Answer:
Marketplace competition drove producers to innovate and improve products.
Some are more desirable because every person has a personal preference that appeals to them and if it isn't appealing to them or if society likes one more, it would naturally draw the to it.
Not really,
It is reliant on the intensity of the attack as well as the power of the attacking nation.
some countries have been attacked and literally never fought back but surrendered if the attacking nation is more powerful in terms of military power.
in case the intensity of the attack can be absorbed, a country can also opt for diplomacy as war is the ultimate sanction in international relation.
in case the country feels it has the capacity to protect its sovereignty then fighting back is the only option.
