 Even so, the classical republicans were sensitive to the particular dangers of territorial expansion. They especially worried that by upsetting the domestic balance of wealth and power, imperial conquest would undermine freedom at home, and accordingly they sought remedies through various cooperative and federal arrangements (Deudney 2007; Bohman 2008). Whether optimally securing republican freedom under modern conditions will ultimately require some sort of global republic, however, remains a topic of debate (see Pettit 2010; Martí 2010; Maynor 2015).
