How do the articles of confederation approach issues of security and freedom?

The problems with the Articles of Confederation are all related to inadequate powers of the national government with too much power for the state. The framers of the Constitution aimed to build on the strengths of the Articles of Confederation but also fix the problems with the Articles of Confederation.  

One of the biggest problems was that the national government had no power to impose taxes. To avoid any perception of “taxation without representation,” the Articles of Confederation allowed only state governments to levy taxes. Foreign governments were reluctant to loan money to a nation that might never repay it.

when world war i broke out across europe in 1914, president woodrow wilson proclaimed the united states would remain neutral, and many americans supported this policy of nonintervention. however, public opinion about neutrality started to change after the sinking of the british ocean liner lusitania by a german u-boat in 1915; almost 2,000 people perished, including 128 americans. along with news of the zimmerman telegram threatening an alliance between germany and mexico, wilson asked congress for a declaration of war against germany. the u.s. officially entered the conflict on april 6, 1917.
