Final answer:
Historical contexts such as alliances, national sovereignty, and economic strategies have influenced decisions to attack, shown through examples from the American Revolutionary period, William of Orange's invasion plans, World War II, and assaults during King George's War and by Napoleon.
Step-by-step explanation:
Factors contributing to Harry's decision to attack France can be considered with reference to historical scenarios where decisions to attack were influenced by various motivations and alliances. Notably, the commitment to alliances played a central role in decisions to engage in military action. During the American Revolutionary period, France's declaration of war on Great Britain and the Treaty of Alliance put pressure on the United States to assist, as advised by George Washington's cabinet. Similarly, in 1688, William of Orange's intent to invade England was motivated by the desire to bring England into his war against Louis XIV's France. Likewise, the desire to protect economic interests is evident when considering Secretary of Treasury Hamilton's reluctance to aid the French due to potential disruption of trade relations with Britain.
In the context of World War II, political stances and the defense of national sovereignty spurred attacks. As Hitler set his eyes on Poland, France and England pledged to support Poland, leading to a commitment to military intervention against German aggression. Furthermore, national pride and defense capabilities were proved decisive during the Battle of Britain, as Britain's successful defense against the German Luftwaffe prevented Hitler from carrying out his plans to invade Great Britain.
Another aspect influencing the decision to attack could be linked to the situation during the 1745 attack on Fort Louisburg in King George’s War, where the capture gave British forces an advantage by inhibiting French resupply efforts in North America. Similarly, strategic decisions to undermine the economic strength of an adversary, as evidenced by Napoleon's attack on British trade routes to Asia instead of a direct military assault, highlight economic strategies as reasons for aggression.
